This will be our third year at our neighborhood swim club...we live in an older neighborhood (no HOA)...and the swim club is just an old fashioned private club. Basic pool (two diving boards), baby pool, grass area, BBQs, playground and two tennis courts. The swim lessons are great, swim team is nice, tennis lessons are cheap, but mostly it's great for the social aspect. We go most weekdays and some weekends. Our club allows you to wheel in coolers and the gas BBQs are always available for use by members -- most evenings there are several families grilling out, sharing wine, beer, etc.. There's also an old fashioned Crap (i mean Snack) Shack where you can get all the candy we remember from when we were kids along with such specialties as Cup O Noodles, Soft Pretzels, etc.
Our club costs around $500 a year (and the first year there's a $250 joining fee). The waitlist is a mile long and they only let in a few new families each year. For us, it's totally worth it...These types of clubs seem to be common in our metro area (although we also have country clubs, big rec centers, etc. too) and ours is a great deal (several others have more expensive annual fees along with much bigger initiation fees).
