Thanks, Gary (and everybody).
Though in principle I approve of bears, wolves, big cats and so on, actually one of the good things about Scotland is that it still has biggish wilderness areas but there are no big dangerous creatures - you can sleep out under the stars whenever you like - there is nothing that can hurt you. Except maybe another human being. There are people who want to re-introduce bears, wolves, lynx, wolverine and so on - no thank you - I prefer to roam without worry and also - crucially - without carrying a gun.
