Andy, that's not a category that I've paid much attention to . I went through some scans on my computer and grabbed screenshots of some listings. Most of these phone books aren't mine...I've traded phone book/city directory scans with a few other people to expand resources for all of us. As I continue to go through our phone books, I'll pay attention to Billiards and Pool listings for you
