When my oldest children were small, we would take walks on the summer evenings while their father was working. We would only walk a few blocks on one direction, but I am sure their little legs thought we walked for miles. The favorite direction was down a sidewalk on residential street that had been torn up and reformed after the roots of a  monumental and obviously ancient tree had grown into and broken apart the once smooth sidewalk.

Holding one hand on either side of me, my oldest children would begin leaping in excitement with the expectation of walking around that tree. As we get older, it is the simpler memories that we seem to cherish most.
