Heres some state parks:
1. Dreher Island State Recreation Area is located on Lake Murray
2. Paris Mountain State Park in Greenville
3. Croft State Park in Spartanburg

They all have rentable shelters etc.Also, many of the the local resturaunts already have bike nights, classic car nights etc etc. Beacon, Kostas, Carolina fine foods, Hooters to name a few. We could possibly represent at one of these. Just tossing a couple of locations out there.
