Making the trek from OK would be rough. We make the round trip to Denton for Vintage in a day, but an 8hr drive one way would require 2 days of travel. Not opposed to that, but the draw would have to be fairly large (50+ people, high entry mostly paid out in prizes) to warrant the extra day of travel and a hotel room.
Regardless of reason, no one has the right to anyone else's body. Ever. Win or lose, you are allowed to offer a handshake but expecting it in return is an entitled position. The reason behind your opponent refusing to shake does not matter. They don't want to touch you, and you have to respect that.
