One morning while entering the MK, the woman a few people in front of us seemed to be taking forever to get thru security.....turns out she had full JARS of PB and Jelly, two full loaves of bread, a huge bag of chips, and several beverages. They made her take them back to her car. I overheard them say it was *too* much.
We take bottles of water for each of us, a few small snacks (granola bars etc) but that adds enough weight to our back packs.
