I just wish there were more of the "Slower traffic keep right" signs along I-25 here in Colorado. Driving to or from Denver is a pain so many times when people think that because they are going 75, they are fine in the left lane. Even if I'm going 85 in that lane passing people, and I see someone come up on me faster, I'll get to the right when possible. I'd try to stay on the right, but thats near to impossible with all the traffic now. I wouldn't be supprised if it's turned into a 6 lane highway for the entire 60 mile stretch soon.
