I was in a very similar boat to you less than a year ago. I had worked intramural and recreation leagues for about 5 years and recently moved to NYC.
I was finding doors shut and difficult to find learning opportunities.
The first thing that really shifted my entire perspective on officiating - like you I was confident I thought I had a pretty good grasp on most things (WRONG I was haha)... was joining Ed Rush's Court Club. I probably sound like an informercial right now haha but seriously I have learned Sooooooo much from the program and the monthly calls (We just received 70 plays on video with detailed explanations of things to look for as a bonus... someone can say the words start-develop-finish to me till they're blue in the face, you show it to me once or twice and it means so much more).

Its an investment but the thing I liked was it was billed in installments of like $98/month for 4 months. Honestly thats like 2 rec games a month so I look at it as reinvesting my money earned to push me to the next level.
I seriously love it -- but also I think I get a free CD if I refer people so mention my name haha. If you have any questions private message me.
Also, where in conneticut are you from? I have a friend about our age (assume you're early/mid 20's) that is making some nice moves in that area that I could connect you with... private message me for his info and if you have any questions about Ed Rush's Court Club
