Amateurs.
I think I have spent more time traveling than anyone on this board.
For example: In 2005 I made Chairman Preferred on US Airways (100+ segments in one year) and I ALSO made Gold status on Northwest Airlines (40+ segments per year). I was platinum with Holiday Inn (have been for going on 7 years) and Presidents Circle with Hertz rentals. That was my busiest year though.
I have more memberships, but those are the ones I use the most. For the last 2 years, I spend most of my time in OH. As I write this, I am installing a system in a Home Depot in Wichita, KS. I still drive my car 30-35,000 miles per year on jobs.
