We’re having a great time on Nantucket — Pippa and I spent a few hours bicycling yesterday, so that my back is quite stiff this morning, but the weather is terrific. We’re having Margaret-made dinners with my Mom, wandering around and pondering what has changed, glad some things haven’t. Whenever I glimpse an undeveloped patch of Nantucket’s scraggly woods or thick, matted undergrowth, I exhort Pippa to notice and remember.
