Thread How cold is "cold"?

Walking the Freedom Trail in Boston in February was one of the most miserable things I've done. That fucking wind man...

Yeah dude, that was one of the dozen coldest days I've experienced in the city.

It's not bad when I'm properly bundled on the bike, with the full face, only thing that gets cold are my hands then, but just walking around in street clothes? Brutal.
 
-30f is cold. I can deal with anything above that. 75f every day would be ideal to me. too bad cnn isn't in san diego
