This isn't just a road side attraction- it's a road over attraction. It's an arch built over the interstate. Inside, you can learn all about early settlers coming out west. You walk through at your own pace, with a headset that tells you about the displays, and changes the narrative when you move from zone to zone. There's a fun part at the end where they have speed radars over the interstate and you can watch it clock how fast people are driving under you- on a road where the speed limit is 75, so people are moving. It's fun for all ages.
