Anybody do this trail? it goes from nogales to san francisco, about 1200 mi. I', havin trouble finding info on it. the NPS site is super vague. No mention of trail markers or re-supplies.

Anyone know anything?

I downloaded the Google earth map of the trail, and like many of the National Historic Trails, it pretty much follows roads, not trails. I don't know how fun it would be to backpack it, but it might be a fun bicycle tour.
