Scotland by train. One of my objectives was to visit the most northerly station in the UK - Thurso.
Wandering around the town I found a model shop !
Durran's is a bit odd - there is a good range of RTR model railways for such a small place, an eclectic selection of railway kits, plastic kits, modeling materials and loads of Games Workshop.
Obviously you're not likely to find yourself in a town four hours north of Inverness by accident, but if you do Durrans is definitely worth a visit. At least you should be able to get the glue or paint for that modelling project you took on holiday.
