Hi Ashley - I don't think you are crazy! If my memory serves me correctly, I met a woman at a party at Salsa South Beach on Frankfort Avenue several years ago. She had mentioned that she & her husband rented large party tents and in the course of conversation, I do beleive she also mentioned that they had a trapeze set up for corporate team-building events. I found her business card - it's for Big Tents of Louisville and it is located in Crestwood. The phone # is 502-241-0904. Of course, I could have had one mojito too many that night and imgined the whole thing!
Good luck - I hope this helps.
Michele
