Minsmere

This was a new one on me, so I just thought I'd check to see what its claim to fame was.

As far as I could tell, it hasn't really got one.

The RSPB lists 180 nature reserves on its website. I am never going to learn which counties they're all in, even if I wanted to, and I'm certainly never going to visit them all.

For most people, I strongly suspect, questions like this are always going to be simply a case of "guess a county".
