My husband and I awoke early to start our long drive. After about an hour, my husband asked me to drive for awhile. I had noticed the policeman parked a block or so back, so when I pulled out of the parking lot where we had switched, I was not surprised to see him behind me. He followed for awhile and then turned on his lights. I pulled over and he claimed I was weaving. It was about 3 a.m., and I suspect he was either bored or assumed a driver at that hour would be either sleepy or smell of alcohol. I was neither, nor had I been weaving. He "let me off" with a warning!
