No but I could have, 56 in a 45 mile zone.
Short 1 mile descent on the tandem. Tucked but not pedaling and no intentions to try to increase the speed. Wife on the back, always very relaxed and goes with the flow. But at that speed, my helmet and sunglasses chattering. Very happy there weren't any squirrels or dogs running across the road.
Don't need no ticket, I hope to never hit those speeds again. Though the tandem is rock solid, 56 was just too fast!
