I'll be interested in the counts during the winter. Today I was at my previous location near the Hawthorne bridge (I commented on it earlier). Today, it rained on and off and the weather wasn't exactly warm, plus it's getting dark sooner. Again, my (very unofficial) 'count' would peg the number of riders at about 10 - 20% of what I had seen during the really nice days.

It will be interesting to see your numbers.
