That is pretty much how it should be all over!!!!!!
Same post, Insert different builders name and I am sure this would work.
Builders love to build, give them resources and they think they are in heaven.
But I can see it already, " I can't afford five dollars, I just bought a $4000 mountain bike, maybe next time"
Seriously I think that isn't a bad idea to be presented to any builder or group of builders. Especially on some high traffic trails. They know who rides the trails.
