Earlier quoted context omitted.
Socialization in the PNW is highly hobby/activity oriented. It's immediate common ground and usually a recreational context. Day to day is more much reserved and insular as we go about our business.
Is that why most advice you see online is to go rock climbing or hiking to meet friends?
Edit: the downside of this, in my experience as well, is getting pigeon-holed in some activity with others. Especially when something like alcohol is involved
