My interest in Marilyns began... because I like climbing hills and they get you to different parts of the country.
My favourite Marilyns are... Quinag (all three of them).
My least favourite Marilyn is... Sgurr a'Choire-bheithe - it rained for the whole trip and we were absolutely soaked.
Do I keep Marilyn bagging a secret? I don't keep it secret but neither do I make a big thing of it.
