Each year in July the local outdoor museum, Sovereign Hill, holds a Christmas in July event called Winter Wonderlights. It's pretty cool fun, complete with snow (well coloured foam, but hey that's fun too). It's nights like these that you wish you were an actual kid again instead of being a kid in a grown ups body.

here comes the snow

Great fun, can't wait to do it again next year
