Time travellers tend to use toilet cubicles in restrooms, to materializing in. A number of people have claimed that they've saw strangers appear in such places. I heard about a restaurant in Chicago that was a hive of activity. So there must be other restrooms in the USA being used. But not all of them are friendly, I've written a post about it in time travellers section of this forum about an encounter with a alien time traveller who stepped out of a portaloo and I confronted.Thanks for trying to help. I hail from USA and would love any advice you have to offer.
