I am sure they are having a long lunch so people won't have to hurry and roll call so it gives everyone time to get there and get ready. It still leaves them with 4 hrs of wrestling and for most that is plenty.
When camps don't have lunch in house they usually have a long lunch.
My son is more excited to meet the wrestlers than having a camp. Usually camps are made up of wrestlers that they didn't get to see.And there are a lot of current wrestlers and future Olympians.
