Located at Twin Falls, Idaho, the Perrine Bridge doesn't look like anything particularly crazy when you first lay eyes on it. At 1,500 feet long and 486 feet high, it's not unlike many other bridges in the country. The thing that distinguishes it from the rest of the pack is that it's the only man-made structure in the USA from which people can BASE jump without a permit all year round. Because of this, it's internationally famous and attracts BASE jumpers from all over the world.
As you can imagine, BASE jumping is extremely dangerous, and numerous deaths have taken place at the Perrine Bridge. If things didn't already sound ominous, maybe the fact that it crosses the 'Snake' River will convince you to stay away. We strongly recommend knowing what you're doing before you make the jump.
