If you take the rope condom off, it doesn't work.

"Yes this block isn't attached, how about I run the rope around a little rock. Maybe it will pull it back."

Add the little rock so you can shock load the bigger boulder when it pulls out.  Are your kids going to this camp?

OK, not the worst.

What's missing? How about a knot?

Mommy let junior rig this, she could see the knot grinding on the rock. Let's hope junior drives better.

It doesn't work if you take it off.
