Yes, I used to cross country a lot. I'm out of shape now, but would dearly love to get back into it.

It's just about the best exercise you can get. You can go fast or slow, you can catch a lot of fresh air and scenery. When you really get going on a straightaway, it can feel like you're flying. It's great.

Make sure all your walking muscles are in good shape before the trip. Some light aerobics can help get you ready for it, too, as you'll want some flexibility incase you do fall. It's a super total-body workout, so be ready to do some deep breathing!

Stay with a buddy, ski in pairs. Wear layers, so you can peel them off as you go (you can get amazingly warm!)...good, UV-blocking sunglasses are a MUST, and sunscreen for lips, nose, and cheeks---you can get windburned and even sunburned pretty fast out there. Also bring a fanny pack and H2O.
