I chase after balloons without a second thought. I break into a full sprint down the street, across a parking lot, onto a busy road, just about anywhere, don't care who sees, don't care who stares. I once caught two balloons on the same day within about 5 minutes of each other. It was a great day.
Spontaneity - the game within the game. Thrills and Joys abound. The rewards can be profound. Play at your own risk.
