So, one thing about Sacramento weather that sucks (yeah, I know all the locals who read this are saying "*ONE* thing?? how about a million!?", but forging onwards...) is the very dynamic temperature range.
Take today, for example. It's a fairly normal day, temperature-wise, so you can presume that what I'm bitching about here is fairly standard for this season. Today I woke up, checked the forecast for later today so I could pack appropriate clothing for working and also wear comfortable clothing to ride home in, and got on my bike and proceeded to bitch and curse all the way in to work.
The reason for this is that, while on my way home today it will be in the mid 80s (F) and riding in anything other than shorts and a t-shirt will be akin to ritual suicide, on the way to work it was the low 50s. Combine that with the fact that I'm still a little tired and riding my bike, and you can guess it felt DAMN COLD! Plus, the wind was against me (of course). I verified it wasn't just my biking-generated wind, but the morning wind was actually against me to the tune of about 5mph or so. Thus I had the joys of wearing a thin t-shirt and shorts in 50 degree weather with the equivalent of a 15mph wind chill directed straight at my face!
So, either I dress for the morning ride and be burning hot on the way home or I dress for the ride home and I'm freezing my tuchas off in the morning. That, my friends, is the definition of "ya can't win".
