Easter Egg Hunt

I don't know if this will work, if it doesn't then just let it disappear naturally - anyone game for an Easter Egg Hunt?

Choose somewhere in the United Kingdom to hide your egg and give a few simple clues to direct everyone. The first person to find the egg is the next one to hide it. If after, say, five attempts the egg is not found then the hider gives the answer and suggests somewhere else. My geography is dreadful so please don't make this too hard

i have hidden my egg in the South West but not Cornwall, at the mouth of a river which gives it its name. Easy peasy, good hunting.
