I just recently went out there myself, didn't see anything, but definitely got that strange feeling when I was approaching the bridge. I'd like to return sometime, though. I got there from E. Orlando area by taking Chuluota Rd from SR50, then turning right onto Snowhill (there's construction in the area where Snowhill turns off). One thing I did notice though, was after the first bend on Snowhill but before Ave.H intersects, there was a dense patch of fog covering the road for about 1/8 mile. When I came back 20 mins later, it was gone, not a trace.
