We "Hit a Wall"

After our big day in Quebec City, we sat down to plan the next day on the town. I don't remember which of us said, "or we could just head for Detroit?" Then the phrase "hit a wall" was uttered. Suddenly it all caught up with us and we were exhausted. We had had a fabulous trip. But we were tired of studying every night as though we were facing an exam the next day. Barb told us that we had twelve hours of driving to get to Detroit, so the next day we waited until she said we had six left and stopped for the night in Kingston, Ontario.
