King Juan Carlos I and Queen Sofia of Spain came to town last March for the opening. So what's your excuse? For decades, one of the largest collections of Spanish art outside of Spain languished in little-known, unprepossessing quarters on the Southern Methodist University campus. The new museum is a tad boring on the outside--generic SMU brick-and-columns pompous--but it's grand, the interiors provide a stunning setting for a world-class collection...and lots of beautiful young guys and gals are strolling the campus. What's keeping you?
