Well, this is not really related to dads but it is an awesome feat on mountain bikes I had to pass along to you guys. My wife and her sister just yesterday, 6/23, completed Ride the Rockies, www.ridetherockies.com. I am so proud of them for completing the 422 mile ride on mountain bikes; it's Blogged at http://rtr.milehidad.com/ . I was the Sherpa and support for Team Double Trouble while my son vacationed at Grandma and Grandpa's!
