an outdoor, designated festival area might be a very good idea, and the OWC/331 govt. center area seems like a good choice.
especially for music events, there's so much whining NIMBYism that it's hard to even consider producing/promoting such events here -- and we're all hungry for them, I believe, for cultural and business enrichment.
when the 4-laning is complete along 331 there, the traffic & parking issues should be manageable ... the current parking at the county facilities is a good start, and isn't in use nights & weekends.
