I did the "First 100" camp out with a couple other friends last summer. As young male college students, spending 24 hours in a parking lot for 52 free meals was a no brainer.
As far as the food itself goes, I think Chick-fil-A definitely has a higher quality product than other fast food places. Each chicken sandwich uses a whole piece of breast meat, as opposed to the mechanically separated patties you get from others. Plus, their honey roasted BBQ sauce really is some good stuff ^
