Take on the long day on your feet

There is nothing more painful than walking a trade show hall especially when you are coming off of a hard night of boozing. I left my house at 4am this morning, arrived in Chicago at 7:45 and then spent the next 10 hours walking a gigantic trade show and now my feet feel like two gigantic smoked sausages and probably smell like it too
Thee issue is that the trade show is all concrete with only a think crappy rug on the top and it has absolutely no give, so you can just feel you feet getting fatter and fatter with every step you take. Two more days left
