Things worth knowing before you buy.
Sizing for wind
Tell us the site and the season and we will size the balloon for it. Wind matters more than most people expect, and a balloon that is too large for the location spends the weekend on the ground.
Helium and lift
Helium lifts less as air warms, so a balloon sized for a mild morning can sit low on a hot afternoon. In hot climates size up rather than down.
