There was a lonely spray skit matching that description after the festivities wrapped up near the bathrooms. I picked it up and brought it back to the camping area. They announced it over the microphone, I left it on the speakers for the rightful owner and continued my consumption of Dale's. Not sure where it went from there... sorry.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." - Mark Twain
