Did the same one day with my 7 x 50 binos. Reached a prime vantage point on a rim and began glassing for elk. Suddenly, there they were and well within range. I instantly dropped the binos only to hear them tumbling into rocks about 15 ft below. Seems I had removed the strap from my neck.
I was too rattled to stick with the elk, and climbed down to retrieve the glass. Scratched up exterior, but still in use today.
