If I could pick any place in all of Busch Gardens to set up a permanent webcam it would be right at the base of the bridge facing the most iconic scene of the park - the Rhine with Nessie, Griffon, and Alpengeist all running. You could also see the boats pulling in and out of the docks.
That scene has to be the most photographed area in all of Busch Gardens history of family vacation photos. Why mess with a good thing. If it makes a good post card, it makes a good web cam.
