Go to a sports bar when your local team is playing. FULL of S's.
I really am surprised that you cannot find many S's. I seem to be surrounded by them. I work in a small office and I am pretty sure I am the only N there. My mostly ISFJ and ESFJ co-workers tend to treat me like some kind of pet...they make sure my office is straightened up, bring me lunch occasionally, fix my clothes, buy me accessories to match my outfits, etc. You know, all those things that SJ's are good at, but I fail at miserably.
