That’s a nice article that has a lot of useful information. However, it is a bit lacking in the snow and/or salt removal department 
I keep a small brush and pruning shears on my bike to clear small spots having debris and rogue vines, but the group clean-ups are really effective in making the trails a lot nicer to traverse.

I cannot stress enough how nasty poison ivy can be; I learned the hard way that the roots and stalks are just as bad (if not worse) than the leaves.
I hate poison ivy more than Judd hates standing trees. I had to take a steroid medication to recover from an allergic response to poison ivy at one point last summer.
