I can see how being extinct and missing all of your soft tissue could cause you to be a little cold in winter, hope the scarf helps keep poor Mr. T-Rex nice and toasty.
First time this winter I've ridden underneath the 27th & Normal Blvd. underpass, nothing fun at all about riding on a sheet of ice like this but slow and steady wins the race as they say.
Don't claim to be an engineer or know much about planning roads, trails, etc. but draining water onto a well used path might not be the smartest thing to do and just might contribute to some of the ice.
