Someone was asking just how safe it is to go spectating at the usedcarparts.co.uk Solway Coast Rally this weekend. Of course, it is perfectly safe - provided you don't stray where you're not supposed to.
Naturally there are plenty of signs reminding you that this is a military base, but it is also fertile agricultural land and since the military don't want exploding coos wandering around, they are awfy fastidious about tidying up after their multifarious activities.
So please heed not just the rally signs, but the others - even the loos can be dangerous! Now you know where the term 'thunderbox' comes from.
