Any day I get to ride is a good day. Even if the ride is less than pleasant the endorphin high I get, the mood it puts me in at work, and of course the exercise more than makes up for a bad ride. Having said that...
Riding the LA River north out of Long Beach there was a bit of high fog, but that either burned off or I rode out of it within 10 minutes. There was an abnormally large number of gnat clouds to ride through this morning, I think I ingested 1/2 lb. of the little buggers rather than my normal 1/4 lb.

I'm getting a new bike that should be here and built up in just over a week... I can't wait.
