We did Phoenix several years ago for Spring Training. We enjoyed it but it was hot. We didn't do games every day, just two during our week there. White Sox park good, we enjoyed the game. Then did Hohokam in Mesa for the Cubs, our seats were right on the edge of a pergola one in partial shade the other in direct sunlight on aluminum bleachers. I think we made it to the 7th inning before we bailed. Temperature was around 100, never tell me again "but it's a dry heat"
Never ran into Tarantulas...
