I remember my father teaching me to drive when I was a teenager. One of his pearls of wisdom was that the ability to drive in the snow does not survive the summer. It must be re-learned each winter.
Amen to that one!
It still amazes me that i used to drive 45 minutes to go 10 miles in a middle sized city. Since I've moved it still takes ~ 45 minutes, but I go ~ 50 miles...
