Oh my goodness when they say STAY BACK 23 FEET from the visiting balloons there’s a reason!!! I mean you’ve seen the video of the guy getting gored by one and its pretty funny but when you’re my size and you get directly under one you can get sucked right up the vent hole! Sure I got bounced around a bit by the whirling blades but now I’m all floaty and gee what kind of gas did you say was in here?
