Ths is an excellent article that I would recommend for everyone. It also made a number of specific references to PTN. In essence, it contends that there will be more acqusitions within the industry as companies try to get lean and mean. Expect more home based travel businesses instead of those in store fronts which is exactly what PTN is all about. In essence, there is a silver lining in the clouds and the industry will bounce back. It always does.
