I used to be a fair weather rider, but as the addiction has taken over, I just can't draw the line. I've found that I don't dissolve (and rain is not significantly more dangerous here - not talking lightning or major deluges), I don't freeze (my hands don't even get numb with reasonable gloves), and I'm more comfortable at 35 than 95 degrees any time.
However, I am **hoping** that my historically excellent good fortune with weather will hold up this week on the GITAP ride! Taking off tomorrow for Rochelle... we successfully stuffed my Xtracycle *and* a recumbent into the back of a Protege with room for two passengers and gear!!! Mirabile dictu!!! (we did a practice run today)
