Sweating it out in Phoenix

Now and then I get an opportunity to travel; probably it is not so much an opportunity, as just doing it. However, I am spending a week visiting family in Phoenix, Arizona.
The summer is next to unbearable; the temperature has been 94 degrees at night and 110 degrees in the daytime, maybe 104 in the shade. Seems like I should have better sense than coming here now.
Last night we went to a Major League baseball game, Arizona vs Pittsburgh. The stadium has a retractable cover which was closed . . .
