Here's one: I've been plagued by unplanned deflation events lately on different bikes, different tubes, different tyres: just plain bad luck I suppose. Snow today but two days ago I was under the sunshine on the wayside verge with the back wheel out, when a campervan pulls up. Whole family pile out (husband, wife and two lads in late teens). Husband walks over, says good morning and then bawls. "Oi you two, fix the puncture!" Lad no1 dives into van and comes over with toolbox and track pump and with lad no2 set to the task. Wife disappears into campervan. Wife then comes over carrying tray with cuppas and slabs of Victoria sponge cake. We sit around slurping and chomping and chatting while boys finish job, put wheel back in and join us. There's lots of nice people out there too.
