Airdome Theatre

There is an error, here. 2nd street in Alton runs parallel to the Mississippi river, about 4 blocks into the city. The place you have located on your map is in the city of Fosterburge. I’m from Alton, and I’ve never heard of an airdome in that community, but I do recall mention of something in the area along those lines. I think you have located the corect place on the map, but then credited it to the wrong town.
