I cringe to see fruit just thrown away by the kids walking to the school near me. Just tossed in the creek. My mother once slapped me because I threw a tiny breadcrust in the fire. "There are people starving in (somewhere!)" Taught me a lesson which stuck.

This thread reminds me of some of the treats of yesterday.
Lard sandwiches with extra salt.
Dripping sandwiches with "Lots of Brown, please."
Sausage sandwiches.
I think we must have burned off the fat. No-one was overweight.

Like Banjoman, I made my first bike from parts scrounged from the tip. My Dad built a caravan(trailer) from bedframes and stuff from the tip, and hand-sawed the timber from used railway-sleepers. He had to buy the tyres and HDF/hardboard, though.
Towed it with a motorbike and sidecar!
