OK I got a 2-fer. Spotted a (canary?) Yellow Z at 7pm on fresh pond parkway in Cambridge yesterday.
I was thinking to myself.... fcuk that color is so much nastier than my mag black.
30 seconds later, I saw a 2nd Z, (in mag black) roll out of dunkin donuts also on the parkway.
You were Asian, and you nodded at me, Mag_Black, was that you?
In any case, seeing your Z right after the yellow one was not only icing on the cake, but it restored my faith in having got a black one!
