from Florida (Lake City)
You will be able to pay at the gate but you must have a van as per the Nat's board rules to enter the nationals. You can even rent a uhaul van and get an air mattress to throw in the back to sleep on.
All other FL events are not as strict.We have one this coming weekend just north of Daytona Beach.
Feel free to message me with any questions you have. I am the FL representative here on Vanning.com for the Nationals. If I do not know the answer,I will find out for you asap.
