Every July, I drive about a dozen students from Connecticut to D.C. as part of the John F. Kennedy Institute program. As we approach Washington, there is a sight that never fails to thrill me. The view of the above structure--a Mormon temple, actually--looming over the highway as we approach it in the early evening each summer is pretty striking, as it's lighted such that it glows an iridescent greenish hue. I'm not the first to think it's a pretty fair substitute for the Emerald City from The Wizard Of Oz. In fact, for years an overpass near the temple displayed a pretty clever spraypaint job: SURRENDER DOROTHY. As we reach the crest of a hill and the spires of the temple appear over the Beltway, the kids on the trip finally realize why I kept referring to "lions and tigers and bears" for the last couple of hours.
