Yes, I know the feeling...I have to keep an eye on SE, East & London boards as parts of each fall in my punt scanning radius.
We generally follow AW regions on here which put Bucks & MK in SE, but Beds & Herts in the East (Anglia), so MK sits right next to the boundary and I've seen MK reviews on both boards.
The SE covers such a wide area on 3 sides of London, it definitely needs locations in the titles of reviews as a punter from Surrey is unlikely to want to travel to MK...or Ramsgate...or the Isle of Wight!
