There is absolutely no reason to get rid of a reliable, high capacity coaster that still gets good ridership and is an area that would not be prime for future expansion. Removing Top Gun makes no sense especially when there are many other areas to expand by. Sure a coaster could go back by Top Gun, but how would you put a few flat rides back there? That terrain is in no way good for a new themed area of the park whcih is why its perfect for Top Gun due to its layout. Also, I dont think anyone is going to complain if Cedar Fair puts a long overdue large steel coaster near The Beast. How would it "ruin" The Beast? Keep in mind you see that other large steel coaster (Vortex) throughout The Beasts layout, and can even see Racer when the leaves are down.
On a side note, did anyone see the American flag they mounted to The Beast's maintenance shed weekend? I thought that was an awesome thing to do.
