In the Arizona area most teams post their try-outs on an ASA forum. I looked on the internet and the following may be a good site to get you started. I did not spend alot of time looking through it but right off it looked like there were teams hosting try-outs. The site is http://www.nj.com/forums/youthsoftball/

Another site listing New Jersey teams is
http://www.girls-softball.com/Teams/NJ/

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

I'd say your best bet will be NJ PRIDE which is located around Asbury Park NJ. In NJ you must commute further to be on a travel team. Unlike PA which there seems to be one every 10 minutes apart. Not sure if they are in your area or age group but Jersey Inferno and Ace Finch's are also very good organizations.
