No other outdoor theater closes August 11th. That goes against every tourism and marketing practice. Most go well into September, others into October. Smart to fully use your demand-drivers.. None come close to the Municipal Theater in Forest Park. It is being crushed by the Zoo and Museums who are now in the nightime entertainment and party business, and always by the Fox Theater. This is getting very old and costs the Region up to $300 million a year in entertainment-driven revenue on and off property.
