I found you at least twice. Sneaky.
Me too, but I thought that was dangerous, going to the same time from two different times? Sure caused Doctor Who problems once but then not another time. But what was the date? Didn't look different to what one might see today.
I think Marty McFly had problems "running into himself" too. Gotta be careful with those time machines. As for the date, no idea. But I love the seeming incongruity of old-culture looking dress, etc. with the cameras and cell phones.
What has been found cannot be unfound.
A dude with a helmet kinda sticks out in a sea of people.
