When we were kids we'd "Skitch" in the winter by swatting down & hanging onto car bumpers & sliding on the icy roads. 35 seemed like a hundred. We'd Skitch behind cars we knew & strangers at stop signs one on each side so we could watch for dry patches. To my knowledge we never got hurt. Here's a great event https://www.trenaryouthouseclassic.com/copy-of-2022-event
