I'm so sorry to hear about your falls and getting banged up. It was really thoughtful of you to go let someone know about that dangerous oil slick. Hopefully it will be cleaned up before some other cyclist comes along. It sucks when your bike gets scuffed up too. So...maybe an opportunity to try a different kind or color of bar tape? Did you love the saddle? Maybe a chance to try a different one.
Heal soon and be well.
