The blue plastic source didn't work out - they have it in stock and at a good price but it's definitely NOT TARDIS colored, more of a powder blue. Which is fine but I think I'd better get some TARDIS colored filament instead, if at all possible.

The new studded bike tires are s-l-o-w but very surefooted. I'll get used to them as I do winter tires every year, but I've been riding little in the last few weeks while getting ready for Windy and some other stuff, and coming from little riding to riding in the cold with full cold weather gear and studs into a headwind was rough. I drove today and will drive tomorrow. Wimp.
