Yes I did similar things. But we survived. And no I don't promote any life or injury risking nonsense, but alas I did as a kid. My worse dice with death was shooting down a road (on my racing bike) called Monks Road coming into Charlesworth, Cheshire non handed and suddenly realised my brakes weren't working but I remembered there was a church and graveyard I could turn into hoping for a safer crash. I turned, skidded and landed near a grave. Knees cut, thigh bruised, elbows shredded etc. Followed by my laughing mates. I was about ten. Later when my dad got home from work he rolled his eyes shook his head and said ill mend your brakes lad. Madness ; )))
