>.> You do know that cameras have been a thing for a while right?

Most of the time they don't go further than the 60s, except for that time they went to the wild west but even then I think the had camera technology. They just never seem to be in an area where someone has one (luckily), but it is a very real worry even if one were to time travel 100 years back.
