Uh... yeah, looking down at the water from the top tier of that tower was quite scary when I was a kid! I think I had to go lower. I occasionally take freight trains down Old Galveston road, next to the old neighborhood. I don't remember any arches, either.
You forgot to mention that you were the 3'rd generation to go there, sis! Of course, I broke the family tradition, sorry! Never heard about it being haunted, though. Could it be... Grandmother? She was a Buff!
