What makes this worth your Saturday is the hands-on format. These fairs typically let you try the equipment rather than just watch, and the mix of organized sports orgs, adaptive gear vendors, and coaches in one place is unusual — it's not a fundraiser gala, it's a field day. Food situation at past comparable events has been food trucks on-site, but bring a snack buffer.

Practical tip: if you're driving, Embarcadero-area parking fills fast on weekend mornings. Get there before 11am or take the T-Third from anywhere on the Central Subway line.

If you only have two hours: skip the main stage programming if there is one, head straight to whichever adaptive water sport has a waitlist, and work backward from there.
