Wednesday was mildly eventful; riding in, I felt so slow, I got off to see if the wheels spun freely (as one does) and for the first time like ever in my history of double-checking that, the rear wheel was genuinely bound up w/ flower petals gumming up the entire fender/tire space. In the process of scrubbing plant material from the fender, I found out it had loosened at the chainstay bridge attachment point. I pushed it up and continued on. At departure time, found my rear wheel flat, so with more incentive to remove the rear wheel I finally tightened the fender into the right position.
Today, 48F and gray.
