A general point on the scene...
I went to my first show the other year as a noobie along with my 4 year old daughter, and was directed by a chap in a fluorescent jacket to a parking space.
Turned out it was amongst a clubs 'reserved' area, and was a genuine mistake. The hostility I received from a few of their members shocked me.
Once I vacated the space (and moved 20ft away) they filled it with a gazebo FFS!
