I just returned from three days in Puerto Rico for a work conference. Beautiful place with fantastic vistas on the north coast. I imagine that the blue of their part of the Caribbean is as beautiful as the blue that surrounds our sad island to the west of them. I would also like to praise an institution that gets bashed very often, and, I think, unjustifiably so: Miami International Airport. MIA is, of all the airports I’ve used, the best. The new amenities in the American Airlines concourse are second to none — the place is very well run. My two forays there this weekend were trouble-free and pleasant. Kudos to all.
