The physics center has several gas grills and lots of picnic tables, which are all in use at the Tuesday night picnic. All the current workshop participants and their families are invited; I think most show up. Steak, chicken, vegetables, veggie patties, and lots of other grilled things are all cooked at once; people bring dinner for themselves or occasionally to share in small groups. The center offers paper and tableware, nice grilling tools, beverages (for purchase), potato chips, and watermelon. If they ever serve anything except potato chips and watermelon, I'm not aware of it.
