I tried out some ice patches on the MUP this morning. I didn't have much choice, they covered it from side to side.
I succeeded on the first one, rode around the second one, because it tended to be a deep puddle and I didn't know how much ice there might be. The third one taught me to do a 180 with my recumbent. It went across okay, but as soon as my front wheel hit asphalt again, the extra traction (plus a tiny bit of change of direction I assume) whipped my rear wheel around real fast. I did okay steadying it with one foot till the bike lost momentum, then my foot slipped out from under me and I went down.
I have to go through that section after dark going back home, and I'm thinking seriously about a bus trip instead.
