Can we push this topic a little further? What about addressing these events from both the perspective as a participant/ volunteer (kit requirements, contact suggestions, what you will be required to do) and as an attendee (t-shirt, sun glasses, maybe a costume)???
Example: I attended Pirates in Paradise for my first and only time in 2005. I was curious and wanted to participate but uncertain who to approach and how to introduce myself. What was required? What is my commitment to the event( I've read Mission's posts about watching a gate late into the night at Fort Taylor)? Is there a cost for meals after hours or in the camp ground (or by invitation only)? So I simply attended the event and had a wonderful time.
Some folks might want to scout out an event first before jumping in. Others are a little braver and go in head first! Some have restrictions especially if coming in for a pirate event from out of time. Some have family that may or may not want to participate but will attend.
I would find these details helpful.
