Since I commute just about every day, you'd think I'd like spring, but this is definitely not the case. The weather is too flaky, and I'll take bad consistent weather over flaky weather anytime.
Since spring has sprung, temps have been consistently below freezing in the morning and warm in the afternoon. As a result, my options are basically to haul too much junk, underdress in the morning, or overdress in the afternoon.
On the few days where it's been warmer in the mornings due to cloud cover, I'm consistently getting rained on in only one direction. Again, the only realistic options are to be overprepared for one direction and underprepared the other.
If the weather has to suck, it's just so much more pleasant if it can suck all day.
