Bicycle theft in Las Vegas is so prevalent that you really have to up your game. Don's had two stolen from where he worked. Used a normal chain to attach his bike to the fence in the parking lot. That was gone very quickly. So he got one of those Kryptonite U-bolt things that's supposed to be difficult/impossible to remove. So one day they came and sawed off the whole section of fence that held the bike (post and all) and took it all away. So he got permission to take the bike upstairs with him and store it there. Most people take at least the front wheel with them. If you see a bike at a yard sale/garage sale with no front wheel, you KNOW it's stolen.
That bike shown above would be gone in 2 minutes. Maybe less.
