I used to attend several trades shows each year. many was the time I would have to pay a couple hundred Euros in excess baggage to carry the samples and literature I had collected during the 2 to 3 day shows. 1 year I did a month long trade show marathon 1 in Spain 2 in Italy 3 in Germany 1 in Sweden then to Turkey then from there. I finally wound up in the far East where I attended 2 more then back to Kuwait for a few days before I decided to take a month long vacation with the wife to Australia where I had thought I might get to relax for a while. So much for that she had never been to AU and wanted to see all of the places I had been telling her that I had visited on my previous trips there 10,000 miles worth of driving and 7 plane trips later I really needed a vacation
