Shirl,
Thanks for your help and time, thats very helpfull the sort of info that will get me looking in the right place. If I get any luck Ill be straight back here with any results. I now have renewed enthusiasm.
I tend to look at deer every other week end and pick some other form of wildlife in between so water courses will be a couple of weeks away yet but fingers crossed.
Thank you once again.
Regards
Rob
