If a zombie infection was in a hospital and you were inside... It would be very bad... You have a bunch of sick people laying in bed... Sounds like an infestation heaven... But why does everyone want to immediately leave whatever area they are in? I don't mean that is your permanent base but if everyone in the entire area is going to one place, it won't be good. I would fortify whatever place I was in and hold out for a few days until things calm down. Then find a more permanent base. I mean if I'm wrong tell me but I don't think it is a good idea to just jump right in to your plan because more than likely you aren't the only one with that plan... Just my opinion
