I am from eastern Washington, and have the same distinction of road uses. Multi-lanes, controlled access is a "freeway" if in a city, but transitions to an "interstate" once outside of an urban area. "Highways" are sometimes 2 or 4 lane roads, sometimes with a divided median, but distinguishablee from a freeway/ interstate because highways could have stoplights and various access points.
Now that I live in MT, "rig" is a word for any motorized vehicle. My aunt told me last weekend that they were always very concerned with having dependable "rigs" because of her commute to work and winter driving conditions.
"the park" means Yellowstone National Park, near where I live. "we're headed down to the park this weekend for some hiking..."
IdahoLakeLady, if you're from Eastern WA, I presume you know what a jockeybox is, no?
I once asked a hotel employee in LA where I could find a a TYME machine. He looked at me like I had 7 heads. I had no idea it wasn't called that everywhere.
