in 2010, Peewee Herman, ZZ Top, and Lorenzo Lamas all went to Sturgis

Plenty of Pee-wee fans flocked to the Buffalo Chip campground outside Sturgis to see Reubens' character perform at a venue also hosting ZZ Top and Buckcherry

I recently heard on a podcast that Lamas sorta left Hollywood acting, and now is a commercial helicopter pilot, and Safety manager for Vezer Industrial, a mining company.
