It was Leap Year this year, meaning the ladies got a turn, so I proposed to my Japanese friend in Lapland - a place that is now special to both of us. It will be snowy next March, but not so cold as in Canada thanks to the Gulf Stream.
We went to Pyha not so far from Rovaniemi above the Arctic Circle.

And because of the snow I was able to propose seemingly on one knee without being too cheesy - I stepped off the walkway meaning that one leg was up to my thigh in snow. The Aurora Borealis was aglow above us (of course that is something that can never be counted on) we were alone amongst the trees and it was oh so quiet. The snow fell in a gentle haze of glass shards (not the usual six sided flakes) and it seemed as if we were being dusted with glittering diamonds.

From there we went to a mountain top restaurant and had a lovely dinner.

You can rent a log cabin in Finland from about 300 dollars a week with log fires, saunas, the works. It's best to hire it from Saturday to Sauturday. (And neither myself or my fiance drive.) The temperature shouldn't dip below minus 10 in March and will normally be just below the 0 mark.

We got our cabin from http://www.pyha.fi/cabins/- I couldn't recommend the people there more highly. They were wonderful!
Pyha and Luosto have their own websites: www.pyha.fi and www.luosto.fi
There's a range of activities there - skiiing, reindeer/husky rides, snowmobiling.
Whatever you do - hope it all goes well!
