Otrfun, you might specify exactly where you were camping.
The onsite camping overlooking the launch field & between the launch field & Alameda is jammed. These are the areas that have power availability. You pay a hefty premium to be in these areas. There are plenty who simply MUST have power, so they pay.
The dry camping area on the other side of Alameda is massive. There is a balloon landing area within this huge space. Weather permitting, the balloons fly everyday. This is why if you miss the first weekend it is really no big deal. They are just as spectacular every other day.
