Perth is an ideal place to live. Centrally-located, with roads branching out to the North, South, East & West, it is within easy reach of - and little more than an hour's drive to - the likes of Callander ... as mentioned by both Ann and Gary ... and Lochs Katrine, Lomond and the Trossachs.
Well worth a visit to the 'Fair City' itself, even - as Gary himself, will vouch!
