............ well i wouldn't dare go back in time when dinasour roams the earth, but that would be interesting!
, you could bring a live sample of a baby dinasour or something, or shoot some vids of how they build the Great Pyramid of Egypt, or how they creat those unexplainable Aerial Images, was it in Mexico? or bring Einstein in the present time and show him how he change the world, why not pinch Adolf Hitler's nose while he is still a baby!
... hey have you seen the movie "Frequency"?.. where the lead actor was communicating with his Dad (who died in an a fire accident/or murdered before he's son was born? or he's son was still young?) from the past thru an old two way radio?.. and he was able to save his Dad's life by warning him what's going to happen? he even told his Dad to quit smoking because there was one point that his Dad had a Lung Cancer... that was a weird movie, reminds me of the TwighLight Zone
