How does one cool off on a hot summer day in San Diego? Perhaps the most obvious answer is to head for the western edge of the county. You know, the part with the ocean.

But maybe you have a couple of little kids who aren’t 100 percent crazy about kelp and crashing waves. And maybe you’re not 100 percent stoked about the prospect of finding a parking spot near the beach, schlepping 300 pounds of provisions and eventually spending hours cleaning sand out of said provisions, your minivan and your children.

What you need is a pool.

In my last column here, I investigated the validity of my perception that over the last decade there has been an increase in families with young kids in Uptown neighborhoods. The results of my research of census data weren’t exactly what I had expected; but they did suggest that certain demographic groups have either been moving their young families here in droves, or getting very serious about making babies during the past 10 years.
