About 48 F this morning. My feet got cold. My Cygolite Rover II charger apparently is no longer working, as the headlight went out before I made it to Dallas (maybe 40 minutes). I still had my Blackburn Flea on my helmet and it was starting to near sunup anyway so I made it OK but I won't be able to for long. I emailed them today to see how they will make it right. I don't think I've had the thing 6 months yet.
