I went there for the past 3 years and it was not a problem. This year in March when I was there they said that one of the guy's of the NNRSI had a problem and yet ski's is not allowed. The guy that was against it was not there but the guy who was there said I could go out and if the other guy ask me why I went out I must just say the other guy said it is OK. What the rule is now I don't know. Maybe you must phone them and ask them. I don't have there number but I will go there next year the same time
Hope this helps
