How do you guys know that's the UK's biggest stag?

If you're absolutely certain that it is, that every single deer has been accounted for and this one is the largest, wouldn't that support Johan's claim that the UK is a big park?

I'm not going to go look up the dictionary definition of "wilderness." My own personal definition is that in a wilderness there's something people don't know about; something yet to be discovered.

It's not possible in the UK for a larger stag to exist without someone knowing about it?
