But but but yours was just French Atlantic rain, not the much tougher
American Pacific one!


Well, it was 50, or 51, or maybe 52 degrees during the very cold and rainy PBP 2007. I suspect it has never gotten that cold along the Pacific coast in the entire history we have been keeping temperature records. Now I realize temperatures do not affect the amount of light generated by the dynohub.. But when your teeth are chattering and hands and body are shivering due to the cold, it might affect things.
