It's not really my scene but Nevada is huge for gambling. They even have slot machines in the airports and gas stations, it's everywhere. And Vegas is where it's really concentrated and super fancy, which big concerts and stuff too. It's big in our pop culture.
So yeah, people can run off to Vegas and get married like Gretna Green but that's not why everyone goes. Like we had a big group from here that went last weekend and none of them got married.
