I wish there were a public swimming pool of decent size (25 yd or m) that I could workout in. I'm somewhat dubious of my enjoying it, though, because I felt as a trained rat for years in my youth spending every night of the week swimming laps and sprints on an AAU competitive swim team. On the other hand, I recall, through it, getting into the zone for the first time in my young life and believe I could easily slip into that beneficial state of mind through the activity once again.
