Yes, you just show up. It costs $7 to get in,
whether you display or not.
You just come in, pick a nice spot and display your work.
You'll end up talking all day long to others with similar
interests. There is security. There is a compressed air
pipe with valves spaced every few feet to supply compressed air.
Steam models can only be run on compressed air- no live
steam allowed.

I hope this helps make you decide to attend.
What kind of work do you have?
