Beat the summer heat at Cool Run in the Mountains. Set at the Big Bear Lake Convention Center, this car and motorcycle show runs 9 AM to 3 PM and benefits local charities. Stroll among hot rods, classics and bikes while taking in mountain air and pine‑scented breeze. The show is free to spectators, and participants can pre‑register; proceeds support community causes. Bring a sweater—it’s cooler up there!
