Going on all day rides on some of the long bike paths around here in DC w/my son in the trailer and my wife beside me on her bike, stopping for picnics along the Potomac, are some of our happiest family memories. My little boy, now 7, was delighted to ride all day in the trailer, even did a few centuries. Sometimes, on a quiet, tree shaded section, he would start singing back there in the trailer to entertain me and my wife... Beautiful moments...
