I looked at the weather forecast for Hallet. Slightly below freezing in
the morning. Going 100 mph down the straight at 30 degrees will give you the
equivalent of feeling of a typical Minnesota winter day.
I don't have much mechanical expertise to offer this group. But having
lived in Minnesota and Northern Wisconsin, I do know a little about cold
weather. Silk long johns might be a great addition to your list of Hallet
Minnesotians call this "silk underwear", but now that I live in California, I
understand the need to state it differently :).
Good luck, have fun, and above all, be safe.
