i am new to the area, and wanted to get a book or 2 about the trails around AZ. does anyone have any info? I was hoping to pick one up at borders or barnes this week, but did not want to get a book that is known to be useless. I was planning on getting an atlas as well. a gps would be nice, but not in the budget. the books just give an idea as to what to expect on the trail. thanks for any input.
