I agree-BLORA isn't that great with the exception of it's Christmas lights display. Now the gun thing is just one more thing I don't like about it. I've never known them to do vehicle inspections though, so you could probably just leave it hidden in your truck....if you got there and forgot to leave it at home.
Uh...who said BLORA is a state park? It's not. It's entirely on Federal land operated by Army MWR, not USACE. USACE ownes and controls the lake and flood easement and leases land for recreational use (city parks, marinas, etc.). Also, the restrictions for firearms on USACE land: Title 36 CFR, chapter III, part 327.13
