Found a hat yesterday afternoon (9/30) on the east branch of the Isolation trail, about 0.1 mile down from the Davis Path junction at a nasty crawl-under blowdown. PM or email me a description and I'll get it back to you. I use gmail and my username there is jtniehof (like here, but with my middle initial.)

(and thanks to the trailrunner who found my hat on the same trip.)
