And it's a LOT of tax dollars to do paving.

Is there a place where they do more than that? I haven't found one yet.

Around here they don't bother rolling the truck across the asphalt they
shovel in. They leave it loose, figuring that traffic will eventually
flatten it a bit.

Right, but they absolutely had to build a very costly nonsensical mural
next to Hwy 50 to make our village appear like El Dorado hills, which it
can never do. Then they shoo'd away Trader Joe's which would have gushed
beaucoup tax dollars into the local coffers. Tax dollars which now flow
into Folsom, from which they build bike paths and maintain road, which
consequently are in much better shape than ours.

There are smart community leaders and then there are not so smart ones.

Texas, Nevada, Utah and Arizona are among states which have a road
system that on average is by far in better shape. Florida also left a
good impression every time I drove there.

Union stranglehold like here?

Grocery stores are not big revenue generators because there is no sales
tax on food. With Trader Joe's there is revenue from alcohol sales,
carbonated beverages, and a few sundry items, but that's about it.

I've noticed what I describe as an elephant truck. It has a large hose
that hangs out in front, from which the driver can emit asphalt aimed at
a hole. Lately the holes have been winning.

Cal Trans is not "shooing away" Trader Joes. The state is not making local land-use decisions. Take your complaints to the Cameron Park CSD Board of Directors.

Also, Trader Joes probably took one look at your community and decided it could make more money in a larger population area, e.g. Folsom -- maybe even pick-up customers from the outskirts of Sacto.

You complain about all the idiots in government, yet you do nothing. The first thing you could do is figure out which government deserves all your carping. Start with looking at local transportation funding. Get on the CSD Board. Make Cameron Park Great Again! SMS has at least made himself part of the "deep state" of Cupertino.

Booze is a major chunk of their sales. They are famous for having
specialty beers and also their wine prices are good. Also, it's not just
abour sales taxes. There would have been sizeable property taxes had
they allowed them to build.

That is exactly the board I meant.

Nope. They were seriously trying to come here because there is a good
market for their stuff. Affluent residents with a serious taste for
specialty items. People who have no problem to plunk down $8 for a
little piece of brie as long as it's the real deal from France.

Not true. I've been at CSD sessions. For other reasons but the results
weren't better. Then I organized a little "resistance" and with a good
dose of media exposure we got things done. The hard way.

Road conditions are mostly in the hands of DOT. Last year they increased
car taxes and gas taxes to "fix the roads". Noticeable results so far? Zero.

If you look at subsidiarity as Jay suggests I think you'll
find your county and township road departments maintain and
plow and patch all the not-incorporated roadways with
various funding sources.

In some counties west of here, you can clearly see the
township lines by the road conditions after a snow while
traveling on the same road.

Just received some 25mm Vee Rubber road tires and it says 7bar 100psi

The Zafiro I have on there now says 100psi min and 130psi max which is
more up my alley.

By how much can a low max rating be exceeded? I like 100-115psi on my
road bike in back. On the front I won't exceed the max because a
blow-out would be nasty and that carries less weight anyhow.

Is this some new California fad, riding offroad on narrow rubber? Whatever for? BTW, I have no problem with low- or zero-tread tyres because I ride mainly on tarmac, even in the narrowest lanes, but surely a mudplugger wants considerable mechanical grip.

There's a good reason not to blow up tyres over the max recommendation: It can get pretty nasty and expensive when overinflated tyres blow the rim apart. It is well worth reading Andy Blance, the designer of Sheldon's beloved Thorn bike, on tyre inflation: see page 36 at
http://www.sjscycles.com/thornpdf/th...a_brochure.pdf

I was a convert to comfortable suspension and inflation regimes already in my motor-racing days, and achieved the same results the same way in cycling: see
http://thorncyclesforum.co.uk/index....16360#msg16360
(which is an extended version of a reply I first made on RBT to a query by Pete Cresswell)
and read on in the ensuing very well-informed engineering discussion about ways of determining the optimum tyre inflation.

In fact, there are all kinds of really good reasons for inflating bicycle tyres to the lowest you can get away with short of snake bites. I run my bike on 60mm Big Apple Liteskins inflated to 2 bar, which is about 29psi and I had two flats in 8500km, by which time the tyres were perhaps half worn. One of those was a snakebite when I hit a pothole at the bottom of a hill at 51kph when the tyres at the end of the month-long reinflation interval were probably down to 1.5 bar, and the other was a nail I picked up by going into an industrial building site to ask the workmen to show me their battery-operated angle grinder (which is a threat to locked bikes).

AJ
Both flats happened right after I announced that in 10 years on Big Apples I never had a flat...
