Just found this thread. I had to get to work early today (7:00) so I left at 6:40 am. It was dark and 19 degrees. The 4 miles on my '72 3 speed Humber was a good time, but my toes, despite two pair of socks, were cold for two hours after I got to the office. I am impressed with how well my heavy tweed hacking jacket keeps out the cold.
