This is a true story from years back but I always will have great memories of it.
I had been traveling across country and had been driving for many hours and was getting bleary from it. So I decided to get off the interstate and find a place to sleep for a few hours, maybe get some breakfast and then continue. I pulled off onto a state road and came upon a small town. Just as I got into town there was a small park so I thought this would be a great place to shut down for a couple of hours and since it was past midnight I was sure I wouldn't get a room so I pulled in and got ready to kick back and sleep. I had to take a bathroom break so I wandered over to the toilets. No one was anywhere at this hour in this little berg so I took a seat and relieved myself. I noticed a penciled message next to the dispenser that said simply "Have fun" and contained a phone number and a time. It had only been there for 30 minutes and I thought what the heck so I erased it and went to find a phone (pre-cell days!)
A man answered the phone and I told him I had got his message. He laughed and told me he was in the cabin 6 up the road a bit if I wanted to come by. I did and quietly knocked on the door of this place with several little cabins surrounding a parking area. Looked like it was something out of the 30's.
