I thought the envirowackos were opposed to balloons being released into the sky?
I have to work, so I don't have the time to research all this. But, here's a start.

This page claims that the release of balloons is illegal in several states and cities, including Virginia and (ding ding ding) TEXAS?
"Mass release of balloons is illegal in several states and cities, including Virginia. Jurisdictions that have laws in effect dealing with balloon releases include:
Connecticut, Florida, Tennessee, New York, Texas, California and Virginia. Cities of Ocean City, Maryland; Louisville; Huntsville, Ala.; San Francisco; and Baltimore.
Legislation is pending in other states including Massachusetts, Maryland, and New York.
