I never drove a Brockway truck but I hauled a lot of lumber from Drake's Branch, Va. to Cortland. It was a 9hr. trip in that 9400 International I was driving. I always liked that run, especially after you passed the 81/78 split and kept on up 81 north, it was pretty up through there and not much traffic.
I'd get off of 81 at some exit, turn left and go into town, then turn right somewhere to get to the lumber treating place. The best part was they'd unload you early in the morning. I'd get unloaded about 6am but there wouldn't be anybody in the office at headquarters until 8, so I'd go back south a couple of exits to a little diner that had plenty of parking and have breakfast. It was either the pizza omelette or pancakes, every time. The pancakes were as big as the plate they were on, and delicious! The pizza omelette had about everything you'd get on a pizza- sausage, pepperoni, peppers, onions, mushrooms, etc- and it was delicious.
That was many years ago. The last time I was up that way the diner wasn't even there anymore.
