Welcome to the board! The Bubbles & Suds group meets on Wednesdays (usually) for a north end dive (T-dock/Edmonds/Clay Walls/etc.) and then a second "dive" involving beer and food at a local spot. Keep an eye on the dive planning forum for the location that week.
If you're willing to travel, the ThThTh group meets on Thursdays for a similar situation - a dive at Redondo or 3 Tree, then another dive at Billy McHale's.
I am normally happy to dive but am in grad school at night these days. When summer comes and I'm not in fire-hose mode I will be delighted to dive with you!
Come to the nerd side, we have pi!
