Tim, luckily I still do have a few LMS close to where I live in Bedfordshire, but have seen quite a number I used to frequent disappear over the years.
So, no I don't have to move west.
Used to visit Yeovil a lot. Bob Banfield's Modelkits shop at the top of town in Hendford has long gone, and so has Hendford Halt the little model railway shop on the road out to West Coker where my late mother in law lived.
