There was a dual carriageway at my maw's. We made ropeswings over that <lucky> and used to dare each other to jump off the footbridge onto the grass embankment at higher and higher points. We also built a raft out of pallets (knocked aff building sites) nailed together with 2l ginger bottles as flotation devices and attempted to sail from Erskine to Clydebank - when that failed/sank, we tried to swim it (more stupid than it sounds). I'd leather my weans if any of them did half the daft ****e we did when we were young.
