What science would that be? Mr. Vandeman is the world class
expert on the impact of cycling on trails and he asserts that the
tires of bikes
on trails is much more damaging then any hiker's boots.
It would be all the real science that vandeman tries, and
fails, to discredit in this article http://mjvande.nfshost.com/scb7.htm
Funny how real research trumps opinion and armchair
quarterbacking by lobbyists like vandeman and you isn't it ?
What "real research" would that be?
Oh, you know, research where people actually go out and measure things, conduct surveys and then publish their findings in peer reviewed publications ... as opposed to lobbyists like vandeman who simply trawl the web and spout drivel.
