Who has gotten those comments before? When rolling out of the driveway for a 25 mile ride on a 30°F, but otherwise beatuiful afternoon...a neighbor comments to me "It's too cold for bicycling. You're crazy."...as he loaded his skis into the roof rack on his car for a trip up to the mountains for some weekend skiing...where it'll surely be significantly colder than the 30° I was ridding in.
