A MORAYSHIRE farmer got a fright when he found a live hand grenade in his field in 2003. Alan Watson, who found the grenade while grading potatoes at his farm near Keith, tapped it against a wooden boc, thinking it was just a dirty spud. “When the earth fell off it, I realised my mistake,’ said Mr Watson. “I just put it down and got clear of the area. I’m glad I didn’t tap it too hard.”
