.22 rifles and real fireworks.
My cousin and I must have littered the countryside with a ton of lead, and I doubt if most kids today have had the experience of a fast-fused firecracker going off in their hand. Wasn't worth mentioning at the time.
Roman candle duels (no one ever got hit but we were really trying) and rolling down a snowy hillside inside a tractor tire into blackberry bushes (took a lot of us to get it back up).
Somehow we made it through. Most of us.
