I had nothing better to do today than look up "Gnomes" and "Winter" together, and I got the webpage for Mt. Buller in Victoria, Australia. Mt. Buller has a "Gnome Roam" activity for children and Dungeon Masters. This is from their site:
"Come and talk a walk with Mt Buller's little folk! The Mt Buller Gnome Roam takes visitors on a tour of the mystical gnome world of the mountain village where they will catch a glimpse of resident Mt Buller gnomes, learn about their favorite places to play as well as some interesting facts about the gnome way of life". Sounds like something I'd enjoy!
