99% sure it was JXJ heading 91N at 7:15 today right at the Longmeadow bend. I was going South and below your Northbound side, so you may have seen a rack or window at most. No front girll/logo it appeared and dark tint(s/z).
Also saw a black LGT w/ bike rack on 91S in Longmeadow around 7:30am today, middle age male driver...? Followed by three more LGT's out of the following 20 cars.
WBM = 18 DAYS!
