i do... but Groton is not the SW part of the state. Believe it or not you are actually on a website that has tons of bouldering information on it. Try surfing the Destination area of the website. As for gyms there are several, a quick google search will get you them. Cheers!
I used to boulder in Middletown quite a bit at 7 falls. It was kind of chossy, but there were ample boulder to hike around and get those fingers fit. PLENTY to do here.
