There is not much in the way of singles, but there are a lot of weekly tournaments that you could play in. Mostly bar box 8 ball but also some 9 ball here and there. Here is a link from Aactive pool league's website. They will be discontinuing this site soon but this link is for tournaments at league locations. http://www.aactivecoin.com/board/viewforum.php?f=10&sid=806740a97a079d7ac6335111dcaab5bf
If you are new to the area, feel free to send me a PM if you need any more info.
P.S. I know AVO had a used Z shaft with a 5/16-18 joint a while ago.
