snow, road salt and/or temps below 30F stop my winter riding.
winter riding is great almost zero other riders I have to wave to.

We already got that snow crap and road salt in last week of October never had that happen before EVER. Still waiting for some mid 40s to appear but looked at extended forecast next 2 weeks and is NOT happening unless the weather forecasters are wrong again. UNREAL how cold and a few snow showers have happened already in October NEVER has done that EVER before. I am SO not ready for winter in terms of house/garage stuff to do and cycles.
I saved 2 days vacation off work just to take off on a mid 40s day but yesterday might have been the last one of 2019. UNREAL, suppose to be normal high of 50 right about now - what is happening?

On that slow reaction times I agree could be dangerous. I drove 3xs to work when 35-37 degrees in morning some 35 miles one way and first time I put my feet down was 25 miles into the ride and my knees were so stiff I could barely get my feet down was that cold nearly locking up my knees from moving down. Man, I am getting OLD! Also hard to use the clutch with 2 sets of gloves on and my finger tips were frostbit as well almost. Not bad the first 10-20 miles but much past that the old body gets too darn cold to handle it when 35 or so out.
