Thanks for explaining.

I think in Texas it is a bit of a sore subject because of parts of Big Bend that could be used but only parts are allowed and I think it is only a small fraction when you consider how huge Big Bend is. I am not 100% sure but it was in reference to Big Bend I first heard about this being a positive change and that was from an IMBA advocate.

I do not know the whole issue since I am very new to mountain biking. Being married to a biologist (by education not trade at the moment) am a little leary of encroaching on any natural place by bike, foot, car, boat, etc..... Especially places where sensitive plants and animals may live.
