One-of-a-kind classics in Connecticut

Catch air in the city’s new indoor trampoline park, which opens Sept. 15 in a historic airplane hangar in the Presidio. The House of Air features the 2X Bowl, a freestyle trampoline structure with two three-sided bowls that’s modeled after skateboard parks; the Matrix, with 42 conjoined trampolines; the Colosseum, where you can try trampoline dodge ball and basketball; and the Air Junior Bounce House, an inflatable structure made for children that’s supervised by “air traffic controllers.’’ The park offers classes for walk-in guests of all ages, “air conditioning’’ fitness programs, and training for professional athletes. Rates are $14 per hour for open trampoline jump time and $10 for each additional hour; online ticket purchases can be made starting Sept. 1. 415-806-7285, houseofairsf.com

Stay at the Windsor Court Hotel anytime until Sept. 30 and a portion of your room rate will benefit marine mammals affected by the Gulf of Mexico oil spill.

This program, coordinated by the Audubon Nature Institute, has been designated the primary responder for the rescue, rehabilitation, and release of dolphins, whales, manatees, and sea turtles along the Louisiana coast. You also get a pelican stud pin, a Gulf Coast amulet, or an oyster with black pearl pendant, all made by renowned New Orleans artist Mignon Faget.
