Are the trails dry yet?

Why is it that every time I build a new bike it rains?! I'm not talking about a few sprinkles, but real rain. Keep in mind that this is Boise, Idaho. For those of you who don't know much about Boise, it is dry. Really dry. So I find it humorous that whenever I build a new bike, it rains for several weeks. Hopefully it will hold out long enough for me to take the Ala Carte out for the maiden voyage tomorrow...
