Dinosaur
An observation to scientists: Who knows if one day we will be far away, through the extraction of DNA and cloning, we can spend the holidays in a Jurassic Park and play with a Tyrant- saurian, ride a Pterosaur in flight or take a Velociraptor for a walk from home. I really hope not, but I'm sure of one thing, I don't think we'll ever reach a high degree of social civilization such as to carry a nice big bag with us if we needed it gno. We would always forget it at home and all in all I think it would never be good stroll.
