. The Mushroom Building, on the north side of Highway 12, was formerly a gas station. It is now a Dassel landmark and during the summer, June through August, there is entertainment at that site one evening each week. A few years ago, I performed there. Each year on Labor Day weekend, Dassel is busy with Red Rooster Days, a tradition that originated in 1959. The Universal Laboratories Building at Dassel is listed on the National Register of Historic Places. There's a wonderful place for disabled adults to work at in Dassel. It's called Red Rooster and my Down Syndrome daughter, Christine, works there every day. They are also involved with the Again and Again thrift store on Highway 12.
