My son went to Michigan Tech in Houghton. We were on the way back south one February when they closed it due to high winds. St. Ignace was a giant parking lot for 24 hours. After sitting there for 12 or so, they started caravanning cars across at 10 mph in the outside (paved) lanes with a state cop leading so nobody got any stupid ideas. I've driven across over 100 times, but taking 30 minutes to do it in high winds was NOT fun. I was in my Magnum, so we were OK, but anything much bigger had to wait..
