Well worth a visit, “B-MoCA” spotlights some of the quirkier nooks and crannies of the arts world with a special exhibition or two at a time. A recent one entitled “Game Changer” featured 11 contemporary artists and their often critical take on sports. Other recent exhibits showcased the work of both local and national artists. Outside on summer Saturday nights, Boulder Outdoor Cinema ([tel] 855/262-9324; www.boulderoutdoorcinema.com) screens cult classics like “Monty Python and the Holy Grail” and “The Big Lebowski.” There is a $5 suggested donation. Expect to spend an hour here.
