60-84...
He just got his wisdom teeth pulled and was recovering. He irked me recently, so I told him get into the car. We drove past base on the highway like we were going to Albuquerque. I have a plaid miniskirt (it's usually a signal) and I wore it on the drive. I randomly pulled over... crawled into his lap... did my thing, crawled over and drove back.
Cars drove by and stuff... I don't know who looked.
There are other places, but this came to mind.
ETA: It was the middle of the day, it was daylight.
