Thanks for telling us about that, Preben.
Your information sounds so useful that it ought to be posted up onto the Roslin Glen page. Could you just copy it and paste it in as a fieldnote?
Here on the forum, that info will be lost in a few days, but posted up on the Roslin Glen page it`ll be there for all to see when they`re planning a visit.
Have you got any pictures?
