Back in 1975 in Portland Oregon, I was in 2nd grade, My mom, brother and I were on the freeway going home. Must have been around 6 pm or so, and it was dark. We were cruising along just fine nothing out of the ordinary until a semi-truck had come up behind us and started flashing his lights at us. I remember my mom just using a few curse words and mumbled under her breath to move along, we are in the slow lane damn it. But the trucker just kept right on our ass and flashing his lights at us.
Now, just to let you know, my parents had recently broken up and my dad is/was a truck driver he has since passed on as well as my mom. But, anyway, my mom got to thinking that maybe this could be my dad in town and saw us and was trying to get our attention, since this was before cell phones.
