If each of the 300 hamburgers was 2 inches,they would have piled up to a 50 foot stack. That is a lot of hamburgers. And, they also had salads, fries and pizza.
How many people were there?
I haven’t seen an official number, but judging from a typical roster with coaches, the team itself would have been at least 100, but that would not include other guests, such as the entire SC Congressional delegation and White House staff.
Two hundred people at least and probably many more, as can be seen from photos.
Any event planner, especially at the White House, would over-order for sure.
