Hmm... Might remove it then... Trouble is - if it WERE bait mortars, there's LOADS of them, and some of them are the size of a 50p, so wouldn't hold much bait!

I have a great pic on my phone (cos I ran out of memory card and didn't have another one with me!) showing a cluster of small indents - should I bother posting it, or just get rid?
