Believe it or not, we’re very much in the back half of winter. There’s still plenty of chilly fun to be had this weekend, however, like at the annual Belfast Ice Festival, when ice carvers create amazing sculptures in downtown Belfast, Friday through Sunday. Also this weekend, Celtic band Scottish Fish performs at the Next Generation Theatre in Brewer at 7 p.m. Friday; there’s a night of Maine electronic music starting at 9 p.m. Saturday at Red Rabbit Bazaar in downtown Bangor; and there’s a Super Mario Kart tournament starting at noon Saturday on the big screen at the Grand Theatre in Ellsworth. And don’t forget the annual Cabin Fever Reliever sportsmen’s show on Saturday at the Brewer Auditorium.
