I always surprises me that in areas of the US were bicycle travel could easy be done all year round, it is highly discouraged and in many of those places it can be very dangerous.
I remember visiting some of those areas and I noticed the way the roads were designed made bicycle travel very scary. In one case, I tried to ride somewhere and I really thought I was going to get killed. All I heard was beeping horns and people yelling at me for a short 10 mile (~16km) round trip errand run.
I guess I am lucky being born in a place that the roads were put in place by cows :) These days, the State Gov started promoting this kind of travel, all that is needed is to fix public transportation after decades of corruption.
Edit: I have even ridden through NYC a few times, to me, NYC it is far safer then places I have seen in those areas.
