I am in Indiana and I was watching a couple just two nights ago and they were heading to the roost at about 8:20. I thought this was a little late, but it stays light out until 9:00 right now. I went back by the next morning and I could see them still roosted in the trees. If you go out and do some owl hoots late in the evening, I would say close to 9:00, then you should be able to get some to gobble and figure out where they are roosting. Hope this helps.
