Its funny, I was just going to log in and say the same thing but you beat me by just seconds.

Ironically, I don't have precheck but I have been randomly selected to go through the precheck lanes each time I've flown out of MCO (which admittedly is just a few times). I think they see a million families with kids and grandmas and tons and tons of baggage and personal items and diaper bags and juice boxes, and then they see ME, a single guy, travelling alone, with one small roller bag... They're sure not sending one of those big families through precheck! LOL
