Rocket Rods were my favorite ride back when they existed. Granted, I was only a kid, but still, they were a rush and provided a great view of Tomorrowland. The only real problem with Rocket Rods was the long, slow moving line.
In order to reinstate a ride on those tracks, they will need to:
a) Create a concept that has a pretty decent capacity
b) Do a lot of construction around the loading tower to create a queue line. The former queue line for Rocket Rods used to go right through what is now Buzz.
c) Create a ride that can handle the unbanked curves of the track, unlike Rocket Rods which had to slow down at every curve, causing stress on the wheels
d) Fix up the track because there are places in the course that are basically overgrown with plants.
