My MC has found himself in a fallout shelter for protection of what many fear will soon be an area destroyed by radioactivity. Their government has failed to provide them with a fallout shelter of their own due to the overall poverty of their specific region, so the residents have taken the time to build their own underground shelter.
I would like my MC to be able to slip out of the shelter through a nearby exit, but was wondering two things:
1.) Would the other occupants of the shelter notice him leaving, given that there are what I plan to be at least one hundred people taking up the shelter itself?
2.) How deep underground would their makeshift shelter typically be, and what kind of exit strategy might a large group of people set up in order to eventually leave said shelter?
Thanks very much in advance, everyone.
