Bankside is having a Frost Fair between Friday and Sunday; I might try to visit tomorrow after work. Last year's was excellent fun and featured an ice slide. This year, as well as mulled wine, ice sculptures and craft workshops in Mongolian yurts, there will be husky dog sledding! - but only if you're twelve or under.
There's also the 'Hug a Husky' tent, where you can have your photo taken cuddling a husky for £4.
Fortunately for me, I already possess such photos: here and here. *smirk*
