There was a sign on the portal for a few days, but this morning, poof, it was gone! Some people say that it got sucked in, and will appear in a news article in 1864 if I look, or maybe an article in 2057 if I look ahead. Others say that perhaps the time travellers needed to keep the note handy to refer to as they try to figure out this new town. Either way, I hope they're doing okay. Someone, and I'm not naming any names, but someone may have to replace the sign.
