When Joe Sinagra's children were small, he wanted to rent a bounce house for a family party. "We were looking around and realized there wasn't a lot of choice," he recalls. So, in 2008, he and his wife, Vicky, started Bounce Around VT, a full-service bounce-house company based in St. Albans. Sinagra, who also works as the sustainability director for Myers Waste & Recycling, says his bounce-house business has inflated nicely: On June 1, it opened new locations in Rutland and Montpelier. Now fun-loving customers throughout the state can rent water slides, dry slides, and bounce houses and castles, as well as snow-cone, cotton-candy and popcorn machines. The expansion came just in time, too: For graduation parties and summer cookouts, bounce houses are a hot commodity.
