I know people were bummed the webcam outside IP has disappeared but there is an app with a ton of traffic cams. MyCityWay, Las Vegas. I know its on Droid for free, not sure about iPhone.
I've been watching road conditions for a road trip in 6 weeks. Some states are better than others, but they all have traffic cams and I am able to see the road conditions. I'll be traveling from Chicago to Yellowstone for New Years. Anywhoo, Here's a traffic cam website for Vegas: http://www.nvfast.org/trafficcameras.html If anyone want a road conditions map just post and I will share the link. It's helpful when planning a winter road trip and in summer it's good for construction areas.
I installed the app. It's ok, nothing really special. I did learn that the cosmo is 5304.23 miles away from my house
