During the time of year that's favorable for bicycling (often late March through early November in these parts), I usually go on an exercise/pleasure ride in the afternoon. (Surrendering my "lunch hour.") This time of year, I typically work straight on through, and then take a longer, more scenic route home.
Also this time of year, traffic noise is compounded by the additional noise from studded snow tires. Those things are noisy, rattling and clattering down the road! Thank goodness most of 'em are off by April. It's a blessing to get away from heavy traffic.
One more observation... after a summer of hot temperatures, a mid-40s day seems frigid. But after a winter of cold temperatures, mid-40s seems like shirt sleeves and shorts weather!
