You'd think Tucson just turned 21, the way it continues partying into the next month, days after our city's official Aug. 20 birth date. According to tucsonsbirthday.org, tomorrow from 7 to 10 a.m., no matter your religion or beliefs, you're invited to pray for Tucson at the top of A Mountain. From 5 to 7 p.m., the Arizona Historical Society is having a special celebration for Cele Peterson and her connection to Tucson. Then on Sunday at 1 p.m. is a screening of Alice Doesn't Live Here Anymore, the 1974 Scorsese movie filmed right here. And if you didn't get cake at Congress last night, you can grab a slice of Alice Didn't Bake This Birthday Cake cake. There's more going on, especially on the weekends. Check out the schedule.
