Way back when, I used to dread the elemental ritual of sharing what I learned from my summer vacation. It wasn’t just that my vacations were relatively uneventful. In truth, even if I’d been interested in gleaning insights from day camp or Little League (which I most certainly wasn’t), I simply didn’t have the perspective to do so. But now, lucky readers, insights seem to be everywhere, even on a classically touristy trip I recently took to Alaska.
