My big shock was in France, where I had a fairly isolated farmhouse with a large gravelled area in front, and I drove home to find myself face-to-face with a boar! These are not nice if aggrieved, but we'd accidentally come face to face so I blasted the car horn and revved the engine, advancing slowly until, fortunately, it decided the car was too big and ran away.
The deer which would sometimes come in to graze at the back from the wood, were lovely - but they ate everything. :(
