This.

Probably the biggest reason I'm pursuing a career now in aviation is due to the opportunities I had to jumpseat on my Dad's trips. Of course those times are long gone now, but I remember them clearly.

The second biggest would be my Mom's idea;
I actually still maintain a logbook that my Mom started for me and contains every flight I've ever been on since I was 3 weeks old. I took over keeping track when I was about 7 or 8 and used to ask for the Flight crew's to sign it. Always ended up getting an interesting comment in there, or invited up sometimes. I havn't entered any of my personal training flights into it yet, but I still do keep track of all the other flights. Its a nice motivation booster to go back through it and check out all the odd-ball places I've been but can't remember...

Its just good to see another Dad doing what he can to give some inspiration to his kid. Whether or not he becomes an ATC is irrelevant. Its the shock and awe factor that kids really don't get anymore I think.
