I had the chance while in France to visit Futuroscope by luck. When I found my self in this Cosmos attraction, a huge sphere room watching the universe as a spectator like you are among the stars, has caused me one of the most undescribable, fascinating feelings in my life.
I advice it highly, if you ever find your self in France, go to Futuroscope!
Most of the attractions are in AMAZING 3D!
Looking up at the nigkt sky has that effect on me too. What makes it worse is that whenever I mention it to anyone else they clearly don't understand why.
