Today's site should be inspiring for kids who love to ride their bikes and parents who want to see the world. Family on Bikes is chronicling a family's planned bike journey from Alaska to Argentina, which is to start in June. The family? Mom, Dad, and 10-year-old twin boys. The bikes? Two singles and a tandem. The length of the journey? 20,000 miles, in about 2 1/2 years.

The kids are going for a Guinness World Record as young cyclists to complete the Pan-American Highway. The parents, both teachers, will school their children on the road and blog about their odyssey, and hope to be hooked up with classrooms where students can follow what they're doing.

Tell us about your bike trips with kids. And try not to feel intimidated by this family's plans. If it makes you feel better, I can barely bike down the block.
