Well, A forest service road far from anything might be a good place to
break down for some, who have a ton of spare parts, a portable shop, and so
on. AAA won't go off of named, numbered roads, and won't venture on to
some of those. If you can reach them, since cell service doesn't reach
them, more often than not.
