Just to be clear, while I appreciate the admiration, it's not a case of wimpiness vs HTFU. I'm not that special.
I'm just an old guy who likes to ride his bike.
I know, you're just willing to take things farther than I'm comfortable or able to without making some bigger changes. I've treated enough patients that fell outside in the ice and snow to want to avoid it myself - if the roads ever clear up before it warms up I'll be out riding again but my comfort/risk zone stops when it's too slippery out.
As for conditions with the bike, economically and storage-wise, I have to make what I have work.
And that's another problem for me, I keep my bike inside at home and work and don't want to bring a wet snowy bike inside. I take my shoes off at the door so I don't mess up the carpets in this weather too.
