OTOH, there are plenty of places where you can look straight down, and see the solid rock you're standing on. BUT you're just a few feet from a precipice, on at least two sides, and there's no railing, no wall, nothing but a whole lot of wind.
I'm going to have to check out the glass thing ... just to see which is more gut-dropping.
There's a place in Minnesota like that...called Palisade Head. My husband grew up near there and he's taken me there on more than one occasion.
It's scares the willies out of me.
But there's some great wild blueberries up there.
Yeah, those are called the trails.
