I'm not the most current on the trail progress. Last I knew the Limekiln section being built will need folks to help build 3(?) bridges. The machine build crew is in Michigan right now, I think.
Once that is done, the other sections will get attention. My guess will be the length from Weedpatch/Bobcat to the existing Hesitation Point, then the other leg of HP. Doing the trail along the road to HP will get the people off the road and (hopefully) curb people pulling the rocks out of Walnut.
No idea on the timelines.
