In order for a waiver to be valid, I believe it would have to be ok'd from the higher ups of which ever company you choose their space...ie the Director of Opperations for Publix...which is located in Lakeland AND I think it might have to be notorized...but Im not sure. Its not as easy as asking the store manager if you can use their parking lot and he/she saying yes. Now, if you can find a company that isnt incorporated, then you will have a much better chance....THEN the first process would be as simple as going in and asking the owner, not some pencil pusher, if you could kick out some cheese to use their lot. Though most people think its impossible, its not as hard as people think to look around and simply ask somebody...now as far as the city/county/local law inforcement is concerned....I wouldnt have a clue. But Im sure theres going to be a problem depending on location/time/date as far as noise and traffic is concerned. But it wouldnt hurt to try.
