I agree. I've pinpointed the location of the tree on the FB Trail conditions tread, only because I'm too ignorant to post a picture of a map here.
I chased away a bonehead who was riding his motorcycle (not a dirt bike, a road one) around on the gravel learners' trail at the trailhead. Didn't get plate numbers but did give him the Mom-Look. (I never had any idea how useful that would turn out to be even after I launched my kids into the world).
I kicked the loose gravel back into place but don't know how that trail was built. If there is some vulnerable infrastructure under the gravel, it may need to be checked.
