So I had been telling Tracy that I'd be happy to show her some of the basics of SCUBA diving in her parents pool whenever we both found some time to do it (and the weather was nice).
One afternoon I grabbed my gear, we stopped off at a dive shop so that I could get a tank, and we wound up doing a weekend of SCUBA diving in her parents pool. There obviously wasn't much to see, but it was a fun time nonetheless.
