Common stops include Banner Boswell Hospital on Thunderbird Boulevard and the recreation centers along 99th Avenue and Bell Road. No chain truck stop is listed in Sun City, so a breakdown usually means waiting at the curb or in a lot. Heat is the main hazard. Phoenix Sky Harbor recorded 143 days of 100°F or hotter in 2024.
