It's a tunnel.
-----------------------
To add some late context to my original post, I've been on every coaster between all the parks here in FL (including Funspot), I've done Six Flags New England, Great Adventure, Over Georgia, and Magic Mountain, along with Knots. Unfortunately, i've never been to BGT Williamsburg, Carowinds, Kings Dominion, Kings Island or Cedar Point, so i'm missing out on a lot just between those parks (Which means i've never been on a giga). So that's kinda where I stand with coasters. No lack of want just more of... i'm in Florida. I've been meaning to plan a trip to hit up some of these places, but it just never happens.
