I still have not been able to relocate this area on a map. I think it was not too far from where Ed and I got the air for our air horns earlier in the day. It was a shame there were not more cars to see us. This part of the Mass felt very much like riding around one of our (Chicago) six-way intersections. Very festive. It allows you to see more of your brothers and sisters. Circular and Cycling seem to go together.Thanks to Matthew Hoover for letting me know the name and location of the Super Hero Power-Up Circle.
