Cold is a problem also. I live 22 miles from where I work and it
takes me 90 minutes to ride that far in the summer (hint: it isn't
level where I live). That would be a long ride wearing a lot of
clothes at zero or below.

Then don't ride a bike if it's too hard for you; not everyone is capable of
it. I'm not sure how you felt this was directed to you anyway; I was simply
pointing out to Jay that a 4 mile commute is usually quite practical via
bicycle. If it's really bad weather, use another means or better yet stay
home or at the inn.

I'm not surprised. Most northerners are a lot tougher than
southerners. :-)

In which case a 22 miler ought to be a piece of cake for a tough northerner
like you! :-)
