I time portaled to Benson Wisconsin June 3rd 1957 3:28pm. This for 16 seconds, and got this quick shot. The little girl would be about 70 now.

Btw the danger of disturbing the path of history by just breathing the air of the past seems not a problem. As timelines we’re discovering are robust.

Look, but don't touch,…much.
I did buy a cool fedora in 1948, and left behind a 2019 $5 dollar bill. No changes happened. Indeed my 2019 five bucks showed up on eBay. This as a strangely aged banknote. …I bought it, and closed that circle. The multi-verse is very tidy.
