Open house is happening April 10-12 (the 2nd weekend of April), with booth hours from 10:30 AM till 4 PM. I am working on getting us 2 booths, like last year (for demonstration purposes).
I've also put us on the list of clubs interested in performing for the mainstage show. The mainstage show happens during the Saturday afternoon of open house and features dances, theatrical productions, and other showcases of talent. Our being on the interest list does not compel us to perform, however I would like to make the opportunity available to any SSDers who wish to participate, before the deadline comes up in late February/early March (I'm not sure what the exact deadline is). I'll try to bring this up at the park over the next few weekends.
