Don t use swimminholes.com. I used swimminholes to ordered a liner back in June of 2011. After months of not receiving the liner I finally had to sue the owner, Kevin Boylen, for the money paid, $1700. Don t be taken like I was, there are better more reputable pool builders out there. I am also not the only one that has had to sue him. Check him out on the MD Judiciary website.
