On Monday night I got back from San Antonio after midnight. I started to unpack, did a load of laundry, took out the trash and watched TV before the buzz in my ears stopped and I could go to sleep around 230 am. For eight days I stayed in hotels, ate in restaurants, went to banquets, rode a rental bike when I wasn't working and generally was either working or exercising from morning till late at night.
I have not seen "The Hurt Locker" but I am told the hero of the film goes back to Iraq after being bored and bewildered by life back home. It is different to ride in the back of a commuter plane next to someone nervous about a routine flight on a sunny day after riding behind the door gunner in a Black Hawk in a sand storm so thick that the helicopter we were flying with was all but invisible.
Business travel has some of the unreality of deployment, although different. Business travelers escape the routine of daily life with long days, too much food and housekeeping done by hotel maids. Soldiers don't have maids, but work long hours and are reasonably well fed. My business travel is over for a while except day trips to DC and NYC and staying over in Philadelphia during events. I think my transition to normal life is a little smoother because of the travel.
