I live in High Wycombe and have a choice of goint to Twyford (Berks), about a 50 minute round trip excluding shopping time or Aston Clinton (Bucks), about 80 minutes round trip. I prefer a shop simply for the ability to browse and the serendipitous chance of finding something I hadn't even considered. I use mail order for things like transfers and nameplates and all those fiddly bits shops don't stock any more, and I use the box shifters for RTR to make my budget stretch farther, like the new Hornby Hall I picked up for £49.00 from the big box shifter in the NW.
But I do miss the now extinct specialist shops wher you could go in and buy a dozen handrail knobs, some 26swg wire. a Westinghouse pump and a set of Romford wheels and axles for a Castle (no need to know the size, the man behind the counter knew it off by heart) only to be asked if I wanted the wheels for the bogies and tender as well and did I want the pins to connect the valve gear to the wheels. Someone will now say they have a shop like that in their neck of the woods and I shall be deeply envious.
Oh well, perhaps when I pass on there will be a proper model shop in heaven?
