To celebrate its one-year anniversary, Asana Climbing Gym is going big—as in big money. The bouldering and rope-climbing venue is holding its Winter Ball, a climbing competition with a $4,000 cash prize, along with a day of festivities including a "fancy dress" costume party—think "prom, ballroom, flapper, wedding, tux, '70s and '80s." Food from Wetos Locos Mexican, sips from Boise Brewing and Indian Creek Winery and rounds of amateur climbing (beginner, intermediate and advanced) to win mountain-scaling swag will also be on offer in advance of the open final at 6 p.m. The $65 registration fee covers admission to the midday party as well as access to the rest of the action, including vendor booths and more. It's time to climb.
