Our college-aged daughter recently started couch-surfing as both a guest and a host and has had some great experiences. I've always thought the best part about traveling is meeting interesting people, and couch-surfing seems like an intriguing way to do that.

It's not really something that "I" have done, but one of my good friends is my husband's former wife. We even take trips and celebrate holidays together. She's a fantastic mother, and I am the luckiest step-mom in the world.
