I was up your way again first two weeks of January and will be one more time in March. After that, I think my NE treks are finito. It was nice 'n chilly!
That loop you are looking at is not one I will be accompanying you guys on my KLR. I've never connected Table Mesa to the Horsethief basin area but from what I've read on here, it's some pretty challenging single track. Make sure you stop and see the lake up there. While it is not near as astounding as some of the stuff you've got in NH, it's still pretty in its own Arizona way.
Horsethief to Crown King will be pretty easy for your group as will the part from Crown King to down S Senator to Battle Flats road. I started NF89 down Battle Flats back to Crown King one time but because I was nursing along with a busted skid plate and there were a lot of rocks, I chose not to chance it and turned back.
Should be a fun loop for you guys! What do you have planned for the afternoon!
