I was like "OK!"
"I was only joking!" he said.
I asked him to stop the car which he did beside a 10 feet wide strip about 40 feet long. I got out of the car and gingerly stepped on it knowing that it was going to be hip deep if I sunk. It was quite frozen and firm but only if I trod carefully. I gently started walking the 40 feet across the high drift managing well until the few steps in the middle where I sunk up to my hips!!! We were laughing our heads off!
I got to the other end and then turned around and ran really quickly and heavily so I sank on every step falling face first several times into the snow!!!!
Steve just kept laughing and saying he wished he'd brought his camera to film it. I fell back in the car laughing, wet from head to foot and we giggled about it all night!!!
