However I cannot vouch for the accuracy or whether they are full-sized tables.
I will put this database back on but if anyone can help in compiling an accurate list, I would of course credit you on the website for your assistance.
Alan, I'd be glad to have access to the snookerusa.com list of locations; you may have listings I've not yet found. I'm going to call each pool hall on my list to confirm it is still open, still has the snooker table(s), etc.
When the list is done I'll make it available in a variety of file formats and post links here and on other sites. If you publish your existing list of locations on the USSA web site then I could grab the page source, edit the list, and then send the edited HTML file back to you.
As time permits I'll be working on a Google Maps-based application to make it easier for snooker players to find snooker tables and get driving directions.
Good luck in the Nationals.
