Park Entry Fee

Have one of these guys ready when you enter the park. I keep the race fees down just a bit because there is an entry fee to get into the park.
  50k Runners- there might not be someone at the gate when you get there, if thats the case, just drive in and pay when you leave. Don't bother with the self payment form at the gate. It will slow things down too much.
Volunteers- Tell them you are a volunteer when you come in. Volunteers don't get charged
