Yeah, you guys are talking about two different types of events. Our local event does have pre entry, but you can sign up at the trials for the same costs. We have had portable toilets at local events for about 2 decades as the total people count is about a hundred. We are having a National next May. Already working on the sections. The Nationals thrive on having a real number of pre-entries, you can enter on site the day of the event, but costs a hundred dollars more!
Security? You guys don`t live in the states. Even our Pastor at Church carries a gun under his Robe.
