Yes, I have a chain saw. Actually, I own two. Chainsaws are relatively inexpensive and they aren't too hard to transport. I have a plastic chain scabbard and keep it stable by jamming the blade between my foot locker and the whee lwheel. I'm still perfecting my winter loadplan. I think chainsaws are an an essential piece of winter wheeling gear. To stay legal, I paid $20 bucks and purchased an annual GWNF firewood collection permit which allows me cut downed trees. I carry my extra premix in a backpacking 1 liter aluminum fuel bottle. That's more than enough fuel for a weekend. No fumes either.
My Panasonic Lumix point and shoot camera has a GPS built-in. It auto tags the location. Great camera.
I'm planning a mega-3 day run for next weekend. There are miles and miles of GWNF forest road in the Reddish Knob area and south of it waiting to be explored. I'm really looking forward to it.
