I grew up in Southern California. So that means every third house on the street had a pool. Unfortunately that was not my house. Fortunately I was a bit sneaky as a kid. What can I say I have an older brother. I learned it from him. Behind all the houses there was the natural wilderness area to create a barrier between our backyards and the next street. At the beginning of one summer my brother, sister and I walked through this wilderness barrier so we could look over the back yard fences and see who had the swimming pools. Then we started making new friends. My brother even took it one step further and figured out when each pool owner was going on vacation. Then treated himself to a new pool every week by hopping the fence.
