These are sure wonders.

based on the new 7. i've actually seen 3 of the 7 and need to see one more before i go back home (machu picchu). otherwise seen the colosseum, petra, and christ the redeemer. also seen the opera house and statue of liberty, but i guess those don't count...

I can see one of the Seven Wonders from my window. : )
