The lad was 16 and thought he would live forever. He had tunneled in the dunes for years without any problem. As I stated in my first post, gently undulating dunes are not a problem. It is the steep dunes that cause the problems.
They get a mark on the locator, 3ft, no problem! But, they have to tunnel in the side of a steep dune, They are a foot away from getting the ferret when it moves away from them, towards the centre of the dune. Do they say we will wait till the ferret comes out? Or, do they tunnel on hopeing to get to the ferret and rabbit before they move again?
All I am doin
