OK, I am still hunting for the pics of the balloon arch while it was on his car, but here it is after we.... appropriated it.

You can see how they tied the helium balloons to the strings. The bald spots are from random balloons popping. The floatiness of the balloons creates the arch.

That's pretty cool!
We're renting (from a business associate) a tent to put in the backyard (protect from the sun, but not rain) and I was planning to decorate a bit with balloons. Not sure if I'll do the arch or not but it's a great idea.
