Self-Reliance Expo 2016

This year there will be a gathering of people with a common interestt at the 2016 Self-Reliance Expo in Lakeland,  Florida. It will be held at the Lakeland Civic Center on September 9th and 10th. Tickets are $10 for adults and children 12 and under are free. Vendors will be there too.
I have never been to a self - reliance expo. The last expo I was at was probably DragonCon. So I am expecting awesome guest lectures and business development.  Toying with the idea of creating some business cards for Eat Your Sand and giving them out while there. Maybe even a custom t-shirt. What do you think?
