Way to go Rob:thumbup:
13.5 miles is a healthy commute for any of us, even if you only do it once in awhile that's something.
As far as the cold weather goes, I have absolutely no room to talk. Here in Arizona if it gets below 50 I am freezing my b@%#s off and can barely get out of bed much less ride my bike. So hats off to you if you can do it, you're a better man than I.
