> I think it is a bit comical to use swimming pools as a volumetric reference when most people's experience with swimming pools has been in a back yard setting or on visits to community pools, which may be any convenient size.

A lot of US high schools and US colleges have Olympic pools.

Especially for high schools it's also true that a lot of them don't. In the case of high schools I think an Olympic sized swimming pool is likely in mid to large cities or there may be one available locally. Swim teams at high school level are probably city school features instead of rural school features. I think there are more rural high schools than city high schools.

I don't know though.

Colleges. Hmmm. I suspect that all state colleges have pools. I am not sure about smaller colleges though. That's an interesting question. I'm sure the data is out there though.
