I've just had to ride my motorcycle home. It was Ok on the A-roads and dual carriageways, but when I got to my local estate, the snow was compacted into sheet ice.
I got off and decided to push the bike home, but my feet couldn't get any grip and I couldn't get the bike to move without me falling over! Fortunately a guy saw me struggling and came out and helped me push it. Of course, it turned out he was a biker as well :-)
