In-N-Out and its fans take the Tough Mudder Challenge in Big Bear Lake
Big Bear Lake doesn’t have an In-N-Out Burger drive-thru, but this weekend the fast food chain has a huge presence in the San Bernardino Mountains community, and they’re not all there to make Double-Doubles.
Bear Mountain Ski Resort is the site of the In-N-Out Burger Tough Mudder Challenge, which started at 8 a.m. Friday, Sept. 5 and runs through Sunday, Sept. 7.
The event is a fundraiser for Slave 2 Nothing, an organization founded by In-N-Out owner and president Lynsi Snyder-Ellingson and her husband Sean Ellingson. Its mission is to combat substance abuse and human trafficking.
