Just got home from a long day trip to Portland and back (110 miles away) for my 6-month eye exam. They check on the growth in my good eye twice a year. The trip up wasn't too bad, just a quite cloudy day. But the trip back was in the rain, and so not as nice, especially when passing the big trucks. But the trip was worth it to get the news that all looked good in the photographs, and tests. Made my day!
None of the trucks I saw carried a spare like this one!
