Some good recommendations but I would consider Kartchner and Biosphere significant side trips (in opposite directions) Kartchner (being a living cave) is a pretty incredible experience you're not likely to find again. Of course Biosphere is pretty cool, too (not really, it's actually pretty humid inside - combined with the desert heat). Did someone mention Old Tucson? I liked the desert museum- they had several docents who always enlighten a visit. As was also pointed out, some fine Mexican food and drinks! :whoopie: WET??? Possibly but it's been pretty dry so, if you are bringing wet-THANK YOU! I heard there was a cooling trend but it was close to 80 today in Phoenix -just ask anybody here for Spring Training!
