Maybe this is a bit older then C&V, but harken back to Camelot (circa 1962). It is spring and we (aged 8-11) decided when we were out on our Columbia and Schwinn balloon tired bombers, that riding was too tame and we needed a change-up - to broom jousting!
Mounted on our trusty steeds at 15 yards apart, one took a broom, bristles forward, a bucket (steel or plastic) with eyeholes for a helmet, and faced the opponent. A fast acceleration and contact, hopefully to mid-chest, with the broom would unhorse your opponent. Worked for two rounds until the contact caused two riders to veer into each other with foreseeable (now, not then) results. Broken spokes, bent fenders, headlight batteries on the ground, cuts and bruises, just as some parents decided they HAD heard a crash and decided to check it out.
Yelling and scolding colored the air, and all bikes, buckets, and brooms were on lockdown. Yet we all managed to survive until the thought of riding without a helmet would be unthinkable. No kneepads, no gloves (helmets-yes
). Fun? You bet!, Stupid? Yes! Memories? Hilarious and lifelong!!!
Plus we all definitely learned how to fix bikes.
