Nice and Toasty in Nashville

Well after 7 hours in a airport ( i know it could have been worse) and finally boarding a plane at 7pm- only to take off and turn back to Denver 20 min into the flight. And then fix the problem.. take off again and then turn back to Denver- right before the beverage service. At about 11:00pm- they decided to switch planes.
And at 2:15am I rolled into my hotel room. At least my luggage was already in Nasvhille waiting for me:) So far the conference is good... too much air conditioning in the rooms- and its like 30 degrees outside. Always enjoyable. I feel like a poll.. whats your most memorable travel experience? ( problems, long delays etc....)
