There's nothing like a late night dip in a swimming pool on a warm summer's eve. I can't even begin to count the number of times I've enjoyed such pleasures -- on camping trips, at hotels, even this week when we're on holiday with my wife's extended family at a spa in Calistoga, California. We've been there in the pools until they kicked us out at closing time.

It seems that I am not alone in my enjoyment of a bit of night swimming -- teens in England have begun indulging as well. The problem is, they're using pools they shouldn't be. The teens use Google Earth to search for homes with large swimming pools, then use social networking sites like Facebook to organize impromptu -- and illegal -- pool parties.

Homeowners have woken up to find their pools full of teenagers who are prepared for a quick getaway on bicycle. Police are "are advising owners of swimming pools to be on their guard and extra vigilant." The sad thing is, at least here in the states, homeowners could be held responsible if someone gets hurt in their pool, even if they were using it without permission.

If I owned a swimming pool, my inclination would be to tell the neighbor kids to use it whenever they liked, but these days, unfortunately, that would be a very unwise thing to do -- I think I would probably have to have a huge fence around it and keep it locked up tight. And where's the fun in that?
