Don't let the first official weekend of summer '13, with its seasonally-appropriate weather forecast, come and go without taking in some great things to do out and about in Fairfield.

Already feeling the heat? Relax with some cool music by the local "hockey" band, the Zambonis, when they open Friday night for the Spaminato Brothers at 7:30 p.m. at the Fairfield Theatre Co., 70 Sanford St. Tickets are $17. For tickets and information, call 203-259-1036 or visit www.fairfieldtheatre.org

If you're not all "Irished" out after last weekend's Irish Festival, take a trip over to Sacred Heart University's Schine Auditorium, 5151 Park Ave., for a concert by the Irish band, the Yanks, at 8 p.m. Friday. Tickets are available at the door, and are $20 for general admission and $10 for students. For information, call 203-271-7765.

Take a walk on the wild side when Milan Bull, senior director of science and conservation for Connecticut Audubon, leads a guided walk through Audubon's Larsen Sanctuary, 2325 Burr St., at 10 a.m. Saturday. He will be joined by members of the Fairfield Forestry Committee, and they plant to identify more than kinds of 30 trees and shrubs, both native and invasive. No charge for members of the Connecticut Audubon Society and $5 for non-members. To register, call 203-259-6305.

Get crafty with a visit to the Fairfield Chamber of Commerce's 51st annual Arts & Crafts Boutique on Town Hall Green this weekend. Hours are 10 a.m. to 5 p.m. Saturday and Sunday, and the fair takes place rain or shine. Admission is free.

Okay, so you're not about to run a half-mile, let alone the 3.1 miles of a 5K run and, impossibly, the 13.1 miles of a half-marathon, but that doesn't mean you can't cheer on those who do both Saturday (5K) and Sunday (half-marathon) when the Stratton Faxon Fairfield Road Races hit the pavement at 8:30 a.m. both days. The races start and end at Jennings Beach. To check out the race courses and for more details, visit www.fairfieldhalf.org
