DazT,
The amount of pink feet in your area, surley you can find the loch they are roosting on, sure the farmers would be pleased if you could keep them off the grass parks, I started wildfowling on the Clyde many years ago, had some good bags down Cardwell Bay area as a lad, remeber Sir Guy Shaw Stewart's keeper used to give me a hard time about access, no probs now-a-days.
