I too live in Indiana but have never been told that. I live rural and don't pull my drapes. I figure the few neighbors who drive by have learned not to look a long time ago.
I inherited the in town house. What's more it is a corner lot. The side where the sun shines is also street side. The bedrooms and bathroom, are shielded so the windows do not need to be covered, but the living side of the house is street side, so they have to be shielded when nude.
Our northern home is rural so we never close the blinds. Our Florida home has windows in the florida room with one way tint and the main house we never close the blinds because our neighbors are mostly nudists as well. So no worries.
Because of two large bushes in my front yard I can leave my front LR and bedroom windows uncovered during the day. At night I close the blinds because otherwise I feel like I am in a fishbowl. Because I have a mostly private back yard I can leave the patio door uncovered pretty much all the time. Side windows covered.
If you need to cover windows for privacy but want more light, consider shoji screens. They transmit a lot of light but are not see through.
Top down, bottom up blinds are also a good option. They won't work in all applications. For instance if a neighbor with a two story home is facing you. But with the bottom of the blinds raised halfway up from the bottom, anyone on the same or lower level won't be able to see you from outside. Just be careful if you are working on a ladder.
My computer is close to a big forward facing bay window. One evening I left the curtains (drapes) open after turning on the light. I was seen by a boy who told everyone in the school, his dad told everyone in the pub and his mum told everyone else. I was outed as a nudist. It actually did me a good turn - everyone around me knows I'm a nudist and I can share stories about my many nude holidays. After that I closed the curtains at night. But they are open throughout the day as are the curtains at all my other windows. I've even cleaned the windows naked. But recently my son was concerned that anyone going past could be upset seeing me during the day. So I fitted viol caf curtains to the study window - they cover the lower half of the window. I can see out but anyone outside can only see my head and shoulders.
Until one day a police officer knocked on my door and informed me that the law is: Nudity inside your home is illegal. If you can be seen by anyone then you can be arrested. I asked if that included a peeping tom, and he said yes. If you can be seen, then you have committed a crime.
The land of the free never ceases to amaze me.
A man's home is his castle.
Not unusual for America. When you've nothing better to do--call the cops and complain about your neighbours loud shower or the fact they MIGHT be nude somewhere in their own homes. Should have asked the policeman how to take a shower or bath with clothes on? Simple crime prevention is everyone's concern. One of my US neighbours complained about my surrounding my sunning spot in the garden with small mirrors to blind his camera and telescope. He didn't mind me sunning nude, but it was his wife who's head I saw on the other end and that's when they both decided to come over and be nude for chatting as they were also nudist but not had a garden which was as private. Very easy to take a fence panel out and agree to share lunches and do both lawns and improve our gardens at the same time. They hadn't realised that all their neighbours were at work during the day, and weren't home themselves. Still laugh about that to this day. Also met a couple nude in a woodland area, both were armed, one with a rifle and the chap had a pistol. The 44 was for any bears and the rifle was for dealing with rattlesnakes. Oh well, interesting life in America.
I can't stand having the drapes closed. We have many trees in the back yard and love to look out. So I keep the front shades closed and the back ones open. I just make sure I don't stand infront of the slider. I was sunning on the back deck once a couple years ago with a sheet over the railing but a neighbor behind me called the cops and they never showed, guess they told her that if you can't see him, hes done nothing wrong.
