The term "Road Trip".
The first time I ever heard that was late 90's.
I guy at work said he was "going on a road trip" to Virginia. I asked what's a road trip?
Said he and a bunch his buddies were going to take his van with a small trailer for their camping gear. I said oh, so you're driving to Virginia? He said yea.
At that point I had already driven many times to The Catskills, Adirondacks, Poconos, (once all 3 on the same vacation), Saranac Lake, Watkins Glen, Niagara falls, Florida, etc.
All those years I thought I was just driving to my destinations.
I never knew I was going on "road trips". Silly me.
