Plans are underway for this year's annual Atari Party, being held once again in Davis, California (near Sacramento, and a 2-ish hour drive from the greater San Francisco Bay Area & Silicon Valley) -- Atari Party 2016!
We haven't picked a date yet, but I wanted to get a thread started here on Atari Age, in case anyone here on the forum is local*, and wants to help out at the show. It will be on a Saturday, from 12pm-5pm (with setup starting at 10am).
Atari Party is a free event, open to the public. There's no selling/trading/vendors at the event (it's typically held at my local public library). I've held it every year since 2009 (a few times were in Sunnyvale), with great turnout from the general public -- not just Atari geeks.
* Though admittedly, folks have been coming from as far as Oregon to help run (& exhibit at) the show, and it sounds like some will be doing so again this year!
