Bricks by the Bay is an all volunteer-run non-profit organization that puts on annual LEGO convention and show. Our next show on August 21, 2016 (10am-4pm, last entry 3pm), is the culmination of a 4-day convention for LEGO builders, artists, and hobbyists. See http://www.bricksbythebay.com for more information.
If you're interested in attending the full 4-day convention, with a chance to show off your models, win prizes, play games, and immerse yourself in LEGO community for a weekend, sign up for that at http://www.bricksbythebay.com/register/ instead.
