Actually wander, no, but they have to walk to the area in which polling is occurring. In the two schools where I usually vote that's the gymnasium/multi-purpose room, which is at the back of the school. You have to go through a fair bit of the school to get there, by default, and they've never seemed to get it into their heads that both gyms have REAR ACCESS fire doors. I went to one of these schools, a lifetime ago, and it would be simple in that school to use one rear door for entry and the other for exit, in order to maintain social distancing.
