32F and very wet from yesterday's rain with lots of leaves on the trail. Frozen leaves are scary. My doctor says I shouldn't ride below 45 degrees because of recently discovered breathing issues. So I negotiated - below 45 i'd wear something over my mouth. He didn't agree but I don't care... except I hate having my nose and mouth covered, drives me nuts. I'm going back and forth between a merino buff and neoprene face mask - they both suck. Suggestions are welcome but I'm sure they will suck too!
