TRAILS:

Before we leave the subject, let me strike a blow for soil-cement
as the better material for hiking and biking trails!
Bituminous surfacing is out-of-place in the backcountry! If you
use it there, I'll hunt you down and make you clean-it-up! Even
on road surfaces, bituminous material is ugly. Cover the stuff
with stone chips or bury it under an inch of dirt...it belongs
under the road surface, not on it.
