I've done the first once and the second twice. They are both worth it!!
I will say - I loved, loved, loved skydiving when I was a 22 year old with nothing tying me down. It would be infinitely harder to do it as a parent now. It is so, SO rare anything happens - but the day we happened to go, the person who went in front of us didn't have their main chute open, and they had to use the backup chute. So it confirmed for me that it DOES happen.
Yeah thats a really good point.....but too late for me I got kids now ha. Was hoping to do it before 40 but those years are running out quick!
