I got Museum and Schoolhouse cleaned up in the 2 hours I spent tonight. Museum has two sections of low branches. They will need some chainsaw action. one you can ride under but they are dead "widow maker" branches that are going to come down anyway and should just be sawed out. The other you might be able to ride under but I am thinking you will have to walk under it, needs a saw as well. On schoolhouse that one at the top of the first climb in the back still needs to be cut out. I got all the sticks off the trail, cleared a few small trees, took out most face slappers, some leg slappers still exist as a weed whacker is needed. So those two loops are good to go otherwise though. The path from schoolhouse down to tunnel is blocked off mostly by trees.
I hope to get back out there tomorrow and Wednesday to get through other loops. Let me know if anyone rides anything.
