i think we all need to stop with the "i'll definitely show up". First of all, we need someone to commit to a certain date and a certain location. After that is set up, we can take a poll on who will or wont be there, set up an entrance fee (to help pay for food/rental facility) and see what happens.
If someone owns a house, just have the get together there. There wont be more than 20 people showing up.
