Little girl has her own obstacle course:

19. Very cool, but that would scare this dad.

My kids are grown and gone now, but 'back when' I was offered a large skateboarding half
pipe. It was in several sections and it took quite a bit of work to get it assembled.
Each section took six guys to carry.
Platforms on each side about 6 feet high with steel grinding edges.
Then my son invited all of his buddies. I was pretty nervous.
Luckily, there were no injuries besides the scuffed knees and elbows.
After about six months one of the other kids dads took it away.
