Howdy. I am from Burlington.
Weekday after work rides are usually at Huntington (right next to my work), Nassahegan (my back yard) or Nepaug (up the street). Sometimes I will get out to the West Hartford Reservoir, but not that often.
Weekend rides on the other hand I try to get away from those places. My favorite ride in CT has to be Middlesex. I just rode Meshomasic sunday, that place is amazing. We hit Trumbull and Westwoods somewhat regularly as well. Case and Penwood on a less frequent basis.
But I am always looking for new places to ride!
Edit: just noticed that you might have been looking for more the road biker aspect of things
