Some dufus left a *huge* golf brolly outside of my flat door. I left it there for nearly a fortnight and as no one claimed it, I did!
I suppose it's actually a cricket umbrella as it says NatWest Cricket on it. Who cares, really. It's huge, study and I like it.
I quite like Murray's idea of spiking it into the ground, so it's handy if and when you need it.
