A few weeks ago I flew to Las Vegas and I was sitting on the right side of the airplane. Maybe 15 or 20 minutes after we took off from Billings I saw this huge lake but I couldn't figure out what it is. It's so big I thought I'd be able to map it with Google Earth but no luck. So I'm asking my listeners to help. Do you know which lake this is? If so, please let me know in the comments below. Thanks!
