There are lots of cool events this weekend in the Bangor area, including a local indie rock show featuring Darksoft, Snake Lips and Burn Kit on Friday night at the Bangor Arts Exchange, Les Ballets Trockadero at the Collins Center for the Arts in Orono on Saturday night, and Celtic band Fodhla at the Next Generation Theater in Brewer, also on Saturday. On Saturday afternoon, Skijor comes to Bass Park for its third wintertime event in Maine. What’s Skijor? It’s like a cross between cross country skiing and dog sledding — just with horses instead of dogs. The fun starts at 10:30 a.m. and admission is $10/free for kids 5 and under.
