I'm planning a day-long road trip in Tulsa, Oklahoma. I need some suggestions for fun places to go that don't cost too much (or anything at all). These can be in the Tulsa area, can you give me at least 5 suggestions and tell me why I might want to include them in my trip? I like art, history, and anything weird.
