Makes me wonder if it's a hazard to aviation? Guess not, nobody seems concerned about that.
But this reminds me of a footnote to the Macy's Thanksgiving day parade I witnessed in '93. I was over on the west side watching them blow up the balloons the night before (Can't do that now...it's all barricaded off.
But then it was wide open).
Two of the ballons that had alreay been blown up were Bart Simpson and Betty Boop.
Well! (Sure wish I had a camera...this would be priceless) The two of them were together in a position that can't exactly be described on a family BBS!
I guess I could say that Bart was wearing ear muffs?
The other thing I noticed...something obvious when you think about it, is the tanks used to fill those balloons were huge semi-truck trailers. Not your garden variety dime store cylinders.
