I have always wanted to do that lol. Maybe I will one day.
Link is dead....sounds fun too. <sigh>
I saw an "authorized" balloon flight on tv about 5 years ago, held be some company or something. They had run out of balloons and called in any nearby residents to donate some helium filled balloons. So the colors and patterns pretty much just got mixed up by then. =P

Damn that would take a lot of helium... I used to blow balloons with helium and it too me 3 big ones (big = about 3 or 4 times the size of a regular) plus about 6 normal helium balloons just to make a onetime use camera float in the air...
but that sounds like fun.. ^____^
