Doug! Welcome to the cat-scene. As you've heard there are options and folks sailing in the area. Podickory is nice but as you found out a bit pricey. Great if you want the amenities. West River is a great place to be. You might also want to check out places like Fairwinds Marina on the Magothy River. Not too far from Podickory, you could get mast up storage there and use the launch ramp. They're under new ownership, not sure what the prices would be. Trailer sailing can be more time consuming, but consider keeping the boat at a storage facility and launching at Sandy Point State Park. There's a beach launch area and trailer launch ramps.
Now I'll pitch West River a bit. You'll find a bunch of experienced cat sailors in Galesville, and you can find bouy and weeknight open class beer can racing as well recreational sailing. Check out

Also, there is a WRCRA Google Group where you can connect with the West River crowd and find out what's going on, including crewing opportunities. And, there is a WRCRA FaceBook page.
Don't be intimidated by the Racing aspect - for the WRCRA stuff out goal is to be laid back enough to not be intimidating but competitive enough to keep it interesting. There's a lot of great knowledge there just waiting to be shared, and folks sail whenever they want in addition to the racing.
And, while we're discussing things, I have a nice Nacra 6.0NA I'm looking to sell.
Where in AA County are you?
Cheers,
Keith
