I don't know how common it is to want to pay site fee with credit cards or whatever, but I figured I'd pass this on since, at the top of our website, it's in red letters:
We will be unable to accept any kind of electronic or card payments on site. Please bring cash or check. We apologize for any inconvenience this may cause. Thank you
Hope to see folks there!
