60s or 70s would be cool. But, i would have to say i would love to see the roaring 20s. I like the music from that era (i work at an italian restaraunt and hear stuff like frank sinatra all day), and those old cars would be fun to drive. Plus weed was legal and the country was very proseperous. Also i like the way people dressed back then. Of course though this would be if i had a time maching or something. I wouldnt want to live forever back then.
