Bus shelter outside UWM student union, 2200 E. Kenwood Blvd.
This was done very recently. I just noticed it the other day when the bus drove over it on Bremen and Burleigh in Riverwest. At first view from the bus window I thought it was chalk and was disappointed when it rained overnight, but it was still there the next day and I was able to get off the bus a few stops early and check it out. I don’t know the significance yet or what 24 means (the RW must refer to Riverwest) but I’ll find out and update this post.
