The 50's first, I would like to see how it was, the streetcars, the life back then.
get a computer laptop from today back then, you can know what will happen and win lottery, horse racing and other stuff.
The 60's hmm ohh yea, the cars back then where cool. And the 70's where nudity was also normal, in a way. The 80's hmm the music heavy metal, twisted sister, joanjett and the blackheart. The 90's with the big cell phone and early pentium computers.
Going into the past you can commit a crime and get back to the present. Like a holdup Since I was born in the late 60's go back in the 50's and make the future, your computer would be like 70 years old and still more advance that anything there is. A master computer who will rule the world *maniacal laugh*
