there is a resource for this kind of info, on the American Model Yachting Assoc. website at www.theamya.org
they have a listing of clubs by state - I took a look around and found 2 clubs near you.
1) Lake Naomi Sailing Assoc. in Pocono Pines. they have a website : //lnsa.org
they race the Laser class rc sailboats.
2) Nepa Model yacht Club , in Hamlin Pa. no website,and they do not say what class boats they have.
go take a look at AMYA , under the boat club list - they had a phone number there to call for info.
if you go to the AMYA site , take a look at the "boat classes" a to z listing , you can get an idea of what is going
on these days with rc sailboats.
hope this helps
