This is from September at Point Isabel. Chester had just discovered the link between squirrels and trees. For several months afterward we had to walk in the part of the park that has no trees; otherwise he would run from tree to tree and be in the next county before we knew it. (That’s almost literal; the distance from Point Isabel to the Alameda County line can be measured in yards.) He’s matured enough over the last few months that we’re gradually returning to the trees. He still inspects the trees for squirrels, but he comes when called — with fair regularity. Squirrel!
