Cosplay Day Out
These are the same basic rules for every event and we should all know them by now.
1. No live steel - this is a public place and there are kids...and cops.
2. No overly revealing costumes - again, public place...
3. No booze hidden in sack lunches (I can't believe I even have to put that.)
4. Respect the park property and park rules. Park rules can be found at their site here.
Other than that, have fun. Remember you are representing cosplayers everywhere so anything bad you do will make us all look bad.
