I think the Serenity pool should stick for the fourth pool, although sometimes I feel it should be called the cigarette butt pool, if you know what I mean, but that would be a negative.
I have a single photo that shows four of the five pools (all except the crab cooker). My challenge know would be to try and get all five. If we could put something like that at the top of the website, "DC 6th Pool" may make more sense. Still hard to believe that we had Wizard confused there for a while. Makes me feel better when I first started coming to the site and sometimed wondered what these people were rambling on about!
