It wasn't avalanche control, it was just traffic and parking. Really, I am grasping at straws here, the access is pretty killer. For my money, if I was going out of this state, I'd probably have to take a good long hard look at the Seattle area myself.
I70 is starting to get a face lift. The areas will never be as close as the Salt Lake spots, but they are going to be making progress on the traffic thing. The tunnel expansion at Idaho Springs will make a big difference. Both when they are doing it (going to suck) and once it's finished (yay!). That project has been delayed until this coming spring which I am okay with.
