As if you needed more ideas to compete with each other for fun shit to do this weekend, on Saturday from noon-4 pm, Pips & Bounce—your friendly local pop-up ping pong... club? Happening?—is setting up shop outside of W+K (224 NW 13th) for a street party benefiting Caldera. Five bucks gets you in to enjoy some casual rounds at the table, plus DJ Mightymoves will keep the mood rolling, and Taco Pedaler will take take of your hanger. Get a taste via this hilariously corny Pips & Bounce "about" video, and if you can spare eight minutes and some sympathy, there's a good little mini-doc focusing on one of Caldera's (ongoing) success stories posted beyond the cut.
