Ooh, how I hate the Colorado Springs airport. Small town people meet main stream travel and world. It is funny to sit and watch those non-savey travelers try to get their large electronics out of their bags, take there shoes off, take their belts off, pack only small amounts of liquid and put them into a clear bag, and then to finally remember to keep their boarding pass and ID on them when going through the metal detector. You could make great reality tv by just setting up camera at security.
The angry travler is also just as amusing. All rational thinking has long disappeared and stupidity is in full swing. Agro people are just to funny to watch. You can see them getting more and more frustrated with no real cause. They stomp up and down trying to get retorical questions answered that won't slove any problem at all.
Then there is he happy family, where the kids are in a fantisy land full to exploration and mom's and dad's chasing after them. The parents allow the kids to be happy as long as possible because they are about to co fine the kids to a small seat for the next 3 hours where the child is going to go from sweet and innocent to noncompliant and unknown frustrations. Hopefully they will wear themselves out and fall asleep as soon as they are on the plane.
Denver got smart and put in a new belgium brew pub so that have the chance to numb yourself before boarding the plane. The best flight is where you fall asleep before take off and wake up after landing. That is the best way to spend the 3 hours of being confined with 300 other people in a 20ft wide flying metal tube. If you can't fall asleep music and a book or a movie is another survival trick. Keep the mind occupied
