In the Arizona area most teams post their try-outs on an ASA forum. I looked on the internet and although I couldn't find any forums the following site gives contacts for ASA in your area http://www.louisianaasa.com/lacontacts.html

Additionally there are different websites designed for teams to easily build team sites. You can usually check out all of the teams listed in your area and even if they are not currently listing try-outs, you may be able to E-mail the team website or get a coaches number and set something up. If not, they all typically either know or know of the other teams and can direct you. A popular team website is eteamz.com then put softball - fastpitch as your sport. Once it comes up you can select by state. http://www.eteamz.com/fastpitch/sites/finder/index.cfm?search=fastpitch. Once all the team listings come up you can look through them to find your age group and check out their site. Good luck

any luck finding a team yet
