I am one of the engineers who went in. Full Tyvek suits, reporators and masks. We were in the basement in hatchways under the floor, under the stage, and between the roof/ceiling. The laddar there does go up to a projection room. There were lines on the floor of the main section beneith the bird crap for basketball/volleyball.
