every year there's a hot air balloon race in my town, and in the past, balloons have landed near my house, so i just posted 4 of these

you cannot convince me it's not legally binding, if a car park put these up you'd better believe they'd enforce it

That sounds like such a unique and fun experience! Watching hot air balloons land nearby must be an incredible sight. I totally get your point about the signs—sometimes it's the small, unofficial markers that carry a lot of weight in our communities. Thanks for sharing!
