Ok, I’ve been around hot air balloons since the late 70’s… I’ve crewed for several, and my sister is a licensed hot air balloon pilot. I’ve never heard of someone taking their bike for a flight. I’ll admit I’ve been inactive for a few years, but I can’t think of one reason why someone would do that. Care to fill me in?
Why wouldn’t they if they wanna?
Well, Ok… that splains it I guess… umm… thanks… 
Bicycle/Balloon Race. Strap bike to balloon, inflate, fly out past line drawn on map, land, TT back to launch field.
I think it’s an East Coast thing, as I’ve only heard of 3 of them & I understand that it’s uncommon for to have paying passengers at festivals in the Midwest.
That actually sounds really fun… especially since you really can’t control where you will land (well, other than somewhere in your flight path).
Any directions that include phrases like “turn left at the corner where the fat kid sells fireworks” and “turn right at the corner where the gas station used to be.”
