I thought that was called a Sound of Thunder. Because the last line went "there was a sound of thunder, then silence." Or something to that effect, heavily implying that the time safari employee killed the hunter who stepped off the trail and on to a butterfly.
I also remember that one of the results of stepping on the butterfly was that all English words were spelled fonetically (typo intentional), a "mistake" I would happily go back in time to commit.
The city is in Indiana. OP thinks it's a cool part of the city because there's an Applebee's and an Olive Garden just a short 30 minute drive away.
