I saw this post on Strava today and I really wish people would take a moment and try to understand the impact they are having by leaf blowing the trails:
It's really detrimental to the trails when this happens. Leaves shed water and keep the treadway from soaking in all that extra moisture. Trails at Upper Paugussett were so good you could ride them after a really good rain storm but now that they are uncovered people really need to let them dry out, now. Not that many riders actually do that any more or seem to care.
If you don't believe then checkout a few of these threads on MTBR:
