All great points. When I was watching the NBA finals this year they had tons of shots of Boston from the blimp. It was awsome at sunset, but once darkness descended upon the city, you couldn't tell which building was which...not to mention what was land, where the Charles River was located, the Zakim, the Longfellow. It just appeared like a mess of yellow Christmas lights. I work near North Station and am used to the surroundings...and I could hardly tell what was what. Such a shame.
