I was walking the dog at the time, before I get any cheeky trails comments! The ball came over the hedge and hit me square in the small of the back. Made me gasp - was as if a large man had thrown a boulder from very close by.
After I'd worked out what had happened and put my fists away, it struck me that maybe I should mention something to the owners. I didn't, but am now wondering if perhaps they should think about a net fence, given that there's a hole right next to a public footpath.
Obviously accidents happen and I'm not about to sue them, but there's no way that's the first time this has happened, surely?
