Even though the temperature may say it's warmer somewhere, that's not the whole picture. Being a North Dakota native, trust me I feel your pain, Brother. The season up there is too short. You 2 seasons. "Winter" and "Not-Winter".
However, NESBA added Brainerd to the schedule, and I WANT to ride there, but
now living in Maryland makes it a heck of a drive to take advantage of it this year.
Back to weather comparisons...
Example. Xmas Eve 2000 was my Dad's last 58th birthday. I got tickets to the Ravens/Jets game for his Bday in Baltimore. At kickoff it was in the 30's. Sounds nice compared to Minnesota, right? The humidit in the air made that game one of the most bone chilling experience in my life. When the sun went down in the 2nd half my fingers turned numb.
A month later to the day he died of a heart attack. I was in Bismarck, ND for burial at the ND Veteran's Cemetary. I believe the temp that day was -25F. I felt more comfortable in Bismarck than I did at that game in Balitmore.
So Hix is right..you'd have very little grip at Barber in January. It's humid there. And you'd be freeeeeezing your butt off due to the humid, bone-chilling cold.
