I had this weird thought yesterday. A friends said "Its worth it at least once."

I think of all those "you got to see it at least once activities" compared to the "you'll want to go back many times activities" and the later always wins and the former is kind of forgettable after a while. Mount Rushmore...forgettable. Crazy Horse Monument....I want to go back. Mammoth Caves...I want to go back. Niagara Falls...eh. Grand Canyon....Hell Yes I want to go back. Los Angeles. Eh.

Granted most of the things I just mentioned are natural parks or places. But they were on my mind. The difference between "at least once" and "you'll want to go back over and over again." Are the "at least once" places memorable and worth it? Probably. But they don't compare to the places you yearn to see again.
