I for one couldn't afford an inground.. soooo for roughly $6000 my AGP was bought, assembled and buried. I didn't do it for the deck, ladder or steps. Eventually I will have a deck to have the area to layout and/or hang out. As for it being moist - I've never had a problem with it being constantly moist around the edges at ground level probably because of the rail caps. As for moisture being 3 ft down, the PB guy said it depended on the moisture in your soil 3 ft down. He claims the pool may last 5 years, may last 10, there is no real way of telling. But I've heard they are starting to make AGP for burying, a lil more pricey tho. Either way, I can now save to have a true inground one day and swim in the meantime!
I have pics of my build and bury but I forgot the title, don't know how to do the link, so I'll be back.......
