Yo, I just got back from Walker. I only had my shorts and a tank top when I got up there and it was 49 degrees out when I started with the sun out. I decided to just go with my button up work shirt and that did the trick. The wind wasn't that bad except in the Parking lot. Recorded this after my ride on my crappy phone. You can view it with Quicktime player. Good times. Man I <3 Walker. Only saw 4 dudes riding out when I started and that was it.
