It is not to late to join the booth. We are printing Brochure's next week.
The cost is $200 - there are already 10 groups on board. With that you get the logo on the sign.
We are printing 5000 one page "brochures" with everyone's logos (on one side in color) and each group's name, URL and Blurb.
We are jointly staffing the booth for the 16 hours it is open. You or someone in your group doesn't have to attend to be "in" though - there is lots of help already. .
Let me know if you are interested.
