Cross Country Skiing Or Snowshoeing: Which One Should I Try First

On Sunday I had coffee with my old work-out partner, Katie. We have decided it's time to  take on the great outdoors for a little exercise. But, should it be in the form of snowshoeing or cross country skiing?

We need your advice. Katie wants to snowshoe and I want to cross country ski. It doesn't mean we can't do both on different days, but we want to know which one is better. Which one is more fun? Which one is a tougher work-out?

I've only been cross country skiing a couple of times, and that was years ago. I can hold my own when it comes to downhill skiing, but cross country is a whole different ballgame. And I've never been on snowshoes.

ANY advice is greatly appreciated. Thanks!
