Jim, there are plenty of cliffs in Britain - pretty much all of south-west England and west Wales in the west, vast chunks of the Scottish coast in the north and a fair bit of Yorkshire in the east. East Anglia and the Thames estaury are pretty flat but aren't really a pigeon-racing area.

I'm afraid the rat-racers are just going to have to accept that there are going to be losses. I'd rather see peregrines than pigeons anyway.
