A couple friends and I are hitting the road June 1st starting in Las Vegas, then moving up the west coast, riding back east to Chicago around June 28th for a small break before making the second leg up through the northeast, down the east coast, and finally through the deep south, Texas, and Arizona to complete the loop finishing in Vegas. We plan to camp (and hopefully climb) a lot, and pack a lot of our own Bulk food/staples, to cut down on food and lodging. Does anyone have any tips, tricks, couches, national parks, or sights they can offer/recommend?

by climbing you mean bouldering & sport? is trad one of the options?
