Sounds like a good excuse for a road trip!
Go to their website, look for their contact information and call customer service. That's your best bet.
Too bad your question didn't come in a tad sooner. We were just there, I could send you one, LOL. Good luck Robert!
I'm not exactly sure, but my guess would be that you can order online
Last time I looked there is not a way to order online however if you call them up very very very willing to help in whatever way they can so it may take a few days to get a shipping answer but I'm sure they will mail you a shirt just give them a call.
