My first DO was an early SeaDO hosted by the fantabulous missydarlin. I knew no one but left the event with many new friends and a thirst for travel that lasts until this very day.
My second DO was the Tour De France DO in Lyon, where we experienced the Lyon Death Climb

First and only paid international flights.
When I went to plan my third DO visit, BooDO in BCN, MD helped me with my routing. I wanted to fly business class to get there using AS miles. I was informed, very emphatically, "You are NOT flying business class on this trip. You are flying BA F!!!" by said MD. Awesome trip from beginning to end which solidified many U.S. and international friendships that continue to this day.^^^
