Titusville is the second best clear-viewing area. About 12 miles from the launch pad, its the closest off-site spot, and the only free location to watch the shuttle.
The view from anywhere in Titusville along the Indian River, running the length of US-1 from Garden Street in the north, down to around Highway 50 in the south, is perfectly clear across the water to both launch pads.
One of the more popular places the aptly named Spaceview Park, at the northern end of Titusville. The Astronaut Walk of Fame is there, too, which is a good way to pass the time while waiting for launch.
