Yes a bit paranoid.
My wife is starting to relax now after two year here. This aint England with the population pressures, this is Scotland with a tenth the people, and thus a tenth the yobs.
I don't give it a 2nd thought. What you do want to consider is knowing how to map read and use a compass. Do not think of relying on a phone. The mountain rescue people get fed up of rescuing those idiots and south of the border you don't get that sort of news. That was another eyeopener for the wife.
