There we go! I had to look up the highest elevation I‘d ever been. I knew I‘d been to Denver, and that I stopped in Vail for a bathroom break once, so I had to figure out where I crossed the Great Divide. The highest elevation on I-70 in Colorado is the Eisenhower Tunnel and I drove it at 18 in my dad‘s 1997 Ford Ranger (red) full of college things and towing a Uhaul trailer.
