I have been walking Allen and Lathrop Streets a lot recently as they are a hot spot of Christmas lights right now. This cryptic message is on the west side of Allen between Kalamazoo and Marcus.

The date is obvious; what to make of the rest? C-R-U5? That last digit is a 5, right?

There’s actually something else I want to get from Allen Street but by the time I got going tonight it was too dark. That will probably be next time.
