Hey Pink,
I've contemplated this question often. I remeber when the "big trip" for Senior week was to go down to the shore for a week. I can truly picture (in about 40 years) kids trying to persuade their parents to let them "go to the moon" for a week or flying off to Mars for a weekend. I could picture the conversation between the teenager and the parent on the com-link.
Tennager: "Hey Dad, could I head out with my friends after graduation tonight?
Father: Sure son. Where are you headed?
Tennager: Umm, well....Ted's already got a ticket for me to Mars. His Dad's got a place near Olympus Mons and I was wondering....
Father: (Intervening before his son can finish) Not on your life. I told you, I would let you go to Hawaii or even to Copernicus on the Moon, but NO MARS!!!!!
Teenager: Awww DAD!!! C'mon man......
Anyway, not to get off the subject but I think it is a small possibility that we will see it before our time is up (I'm 38). However, I do feel that our children will definetly be tourists to the moon. And our grandchildren may take weekend trips to Mars.
