I've been doing a lot of reading tonight. Apparently Natural Bridge is a SPNP--state park nature preserve.
"Dedicated Dec. 16, 1981, Natural Bridge State Park Nature Preserve today consists of approximately 1,188 acres and is located in Powell County. The preserve lies within the boundaries of Natural Bridge State Resort Park. This area was dedicated into the nature preserves system to protect a significant geological system and rare species habitat."
Apparently I was illegal (but constitutional in my opinion) toady.
