Why, there are over 4 million dog bites reported annually and there are recorded instances of dogs killing humans dating back to 1887. -- cheers, John B. |

Note: The correct strategy when approaching a squirrel is steer directly at the squirrel. This may seem counter-intuitive, but does work. Squirrels are incapable of running in a straight line for more than about a meter. As you approach, they have the irritating habit of crossing the road perpendicular to your line of travel. They invariably reverse direction at the last possible moment, even when they are safely across the road. This unpredictable behavior is the origin of the term "sqirrelly". The only certainty is that when approaching a squirrel, it will NOT remain in its initial location for very long. Therefore, the best way to not hit a squirrel is to aim directly at it. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Think of it, swords mounted on the wheels to masticate attacking squirrels. Why, they might even have a secondary use to prevent those close passes that some are mentioning. https://en.wikipedia.org/wiki/Scythed_chariot It might also serve as a protection against marauding mountain lions. -- cheers, John B. |

If you're planning to chase squirrels on telephone cables with your bicycle, methinks some practice might be a good idea. You can add the squirrel later: https://www.google.com/search?q=bicycle+on+tightrope&tbm=isch Hint: Remove the tubes and tires. Ride on the rims. I live on the side of hill which puts the power and phone lines at the same elevation as my desk. Watching the antics of the local squirrels is a regular pastime. Mostly, I'm interested in the regularly scheduled cat versus squirrel versus Steller's jay competition. When there's danger on the ground, the squirrels will traverse the area using the power and phone lines. You're correct that they do travel in a straight line as the phone and power lines offer no other alternative. However, they never go very far at one time or at a constant speed. There's no continuous rush, but rather a series of short sprints. When on the ground, they do much the same thing, but with the addition of sprints in random directions. Incidentally, we have gray, brown, and black tree squirrels. They look much the same, but tend to act somewhat differently. For example, the gray squirrels are fairly wild, while the brown squirrels are quite friendly. No clue on the black as they tend to be rare. We also have gray and brown ground squirrels. A true American squirrel would be red, white, and blue. I haven't seen any of those. https://s-media-cache-ak0.pinimg.com/736x/59/58/86/595886a3cc7d9a6729c098c678e36ea4.jpg -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

The comment was in reference to squirrels only being unable to run more then a meter. Thai squirrels can run at least 15 meters.

There's no continuous rush, but rather a series of short sprints. When on the ground, they do much the same thing, but with the addition of sprints in random directions. I suspect when one is "prey" one is not genetically engineered to run long distances in a straight line. I think Darwin's theory will suggest that those who run in predictable paths may, very rapidly, be eliminated from the gene pool. The cockroach tribe, that apparently has existed for 320 million years always run about in short bursts.... and (bicycle content) always stay close to the outside edge and never, never "take the lane".

(one can only speculate whether "melanistic man" is a politically correct term ;-) And according to the Wiki, Red squirrels, which I thought I used to shoot as a kid, are a Eurasian creature, not an American, and what I used to shoot were likely fox squirrels :-) (proof positive that anecdotal information is worthless ;-) -- cheers, John B. |

Well, sure, they can run straight on a wire, but that's cheating. I know some squirrelly cyclists, but they could probably ride straight if you put them on a railbike. http://rrbike.freeservers.com/ -- - Frank Krygowski |
