Most gym rats know this but that's when all the New Year's resolutions show up, and about how long they last.

Depends on the gym of course, but still....

I lived in Evansville, IN (very interesting town and best place I've lived in the Midwest) for 2 years and got to work out in a gym called The Pit, a gym like no other. The 'aerobics' equipment was one Schwinn Air Dyne and a couple of weighted won duffel bags. Some of the members were competitive powerlifters and competed as far away ass Russia. 

Also, in some gyms, as with the New Year's resolutions, when school let's out if the price is right parents park their kids there with summer memberships in effect making the gym their babysitter. There's no sense in going to a gym where school age kids bogart benches abd sit in front of a mirror popping zits.
