Our T.C.'s use many methods to reduce erosion & control washouts on the
sandy/ gravelly climbs & descents with varying degrees of success.it's an on-
going battle.i propose another tactic without knowing if it is permissable or
effective:calcium chloride.spread the flake with a fertilizer spreader , wet down
with a pump sprayer ( with water hauled in lidded 5 gal. buckets in a wheelbarrow)
or use brine.until it soaks in the soil it's nasty stuff if contacting skin or bike
parts for sure,i get that.i've been caught up to & passed by the O.C.road com-
mission tank truck while climbing Dutton Rd.anyways , thought i'd put that out
for comments.NOTE: i'm not trying to "dumb down" trails, simply to sustain them.
