Well,

Thanks for the info, now I don't need to do the hard searching about that. You also brought up a good point. I never thought about heavy duty ballons as floation devices. Now to just find some that will do the trip and be durable enough.
If you contact me privately, I will let you know what my travel plans are thus far. They may change on me slightly, I'm at the mercy of government contractors and they make my travel arrangement/plans.
What airline do you fly for?
