I lived in CT for a couple of years. Made many good bicycling friends. But in general, I find the folks in CT to be the least friendly folks of the 5 states I have lived. I also found the motorists to be the most aggressive and many of the roads having short site lines and many curves.
The only other State I felt the same way is S. Carolina. I do find the people there to be very friendly but not when they get behind the wheel.
One last comment. In all of my touring, which is nearly every state, when I do talk to a local, they almost always say 'our drivers are rude and dangerous, be careful' I think it really says we need to move to protected bike lanes.
