heh ... I wound up doing that on Wednesday, when the Valentine's Noreaster came to Boston. There's a section of my commute where a four lane main street crosses over an eight lane interstate, and the cloverleaf can be a trick to negotiate even in good weather. There's a MUP that runs parallel, but I'd been ignoring it during winter. Then, after 9 miles into the commute and not being able to break more than 12 mph, I figured it'd be safer to get on the path.

Probably made it about 100 yards before snow got too deep and packed to stop me dead still (no studs on my tires, and I just wasn't getting pedal traction). Pushed the bike for another 200 yards before saying frag this and walked back to the street and took my chances with the cloverleaf.

So, 'roaring' down a 6% gradient at 15 mph with hail in my face and merging highway traffic weaiving past vs. trudging along 2.5 miles of dogsled heavy snow ... still can't decide which one was the safer choice.
