I'm not going to have time to build a launch platform before the party. I plan to use a pulley and pull the kids up from the low point. Adults will have the option to clip in from a latter :-)
I think ziplines and harnesses add 20lbs to images.
Mika pocket holsters work just fine!
First AND second armed traverses of the zip line. Woot.
And I went ahead and wore clothes due to all the women and children around. No need to make everyone throw up.
And so you can judge by scale - the woman holding the baby in the background is my wife. She's 6'1". The baby is just under 18 months old and you can see how much of her that he takes up - even with legs not extended fully. He's gonna be a tank. Oy Vey.
