I just reserved a canopy for the MSRH event and saw that there were only 6 available left. The only other name I saw on the list was Sean's.
They are $80 for the weekend and you can register here:

If y'all are looking to rent one for the event, I'd suggest doing so ASAP.
Just a short 2 3/4 months away!!!
