There's no better rite of summer than spending a blistering-hot Saturday or Sunday casing garage sales looking for toys, trinkets and good buys. But, darn it if garage-sale-hopping wouldn't be even better with something to cool you off -- something like ice cream. At least that's what Dalene Walker and Myron Peterson were thinking when they decided to let people hold garage sales in the parking lot of their northwest Denver Dairy Queen franchise. They got the idea after holding their own garage sale in the lot, which faces the high-traffic 38th Avenue, Peterson says, adding, "I don't know of any other Dairy Queen that does this." Holding a sale in the lot is free, and although not a lot of people took them up on the offer last year, the couple hopes to have a blizzard of activity this summer.
