I'm not sure which "
...point that ends nearest Tucson...", you mean, but... You're right, that's quite a bit of mileage. There's not a lot of
anything out there. Plan carefully!
No matter where you decide to end your hike, there's a LOT of rough mileage in that section of Arizona, and not a lot of dependable water.
I'm available on Monday, the 26th of December (state employees have the day off! (Thanks, taxpayers of Arizona!)). I presume you'll want a lift from your hotel to the north end of the Alamo Canyon segment - # 17.
I'd be pleased to pick you up, drive you to the PicketPost trailhead, and hike a few miles with you. IM me, and let's chat.
