As we approach the weekend, we are enjoying an embarassment of activities from which to choose. The Aspen Ideas Festival continues, with tickets still available for its public offerings. The Aspen Music Festival and School opens tomorrow night, June 30, and over the next eight weeks, will present more than 300 musical events. Theatre Aspen is presenting Mama Mia and the second show, Buyer and Cellar, begins July 7. The Aspen Saturday Market continues until early October, and of course white-water rafting, biking, golf, hiking and every other sport imaginable is just outside your door at Aspen Square!
