Jan sent in this info. Thanks for the first info about Rhode Island!
Here's a link to a couple of slope sites in Rhode Island - yes, RI. Provided by DrBill. Haven't flown there myself. http://www.risoaringclub.org/
Jan says "It's been a cold and rainy summer out on the Cape so far with very little chance to do any slope soaring due to closures. Looking forward to Labor Day.
