1. Are the authors mountain bikers? They seem to be promoting mountain
biking -- trying to make it seem environmentally acceptable.

As usual, if it doesn't agree
with you, it's not true. What
is your point?

BTW -- you can't reference a
non-published paper (such as
all of yours) as
'discrediting' something if
it's not peer-reviewed. But
you knew that.
