In summer 1986, I took a solo road trip from the Bay Area to Portland, Oregon. Late at night on my drive back south, I pulled into a rest stop on I-5 intending to sleep in my car for a few hours before continuing. I was a poor college student at the time and didn't want to pay for a motel. Another guy pulled in next to me, cruised me, and we ended up spending the night together fucking in the front seat all night. He was on his way from Seattle to San Diego. In the morning we just said goodbye without exchanging numbers. This was years before cellphones and the internet.
A year later, having just graduated from Cal, I was on my second night in Amsterdam at the start of a two-month European vacation hanging out at a bar on Warmoesstraat when the same guy walked in. We both recognized each other, started laughing, and had a few beers. We ended up in bed together that night at his hotel. More comfortable than the car.
