Summertime, and the cultural edification is easy. Chicagoans who missed the storefront hits of the 2009-10 season (or who just didn't feel like leaving their house in February) can catch up with the Park District's summer-long program of one-week remounts. This week, BoHo Theatre rolls into town with "The Glorious Ones," a musical about a troupe of 16th-century traveling players.
