You guessed it! We hiked all the way to the top of Stone Mountain with the boys yesterday. Wolfgang pushed the stroller up and also wanted to carry one of the boys in the baby back pack carrier too. We picked an extremely windy day to go up, but they survived. If anyone out there is reading and on the fence about buying a BOB Revolution jogging stroller, you should just go get one. It is awesome! It turns on a dime and you can push it with one finger. You need a few more fingers to get it up Stone Mountain, but that is what Wolfgang is for. (He knows I married him for his muscles!)
