A zucchini "drive by" sounds hilarious! Although I'm sure it's not a laughing matter for the people who end up with unwanted zucchini on their lawn! I have never heard of such a thing!
I can totally understand how it could come to this though. It did not surprise me at all to find out that zucchini is a common bumper crop. I grew zucchini for the first time last year. I only planted one seed, and the plant that resulted was huge! I didn't even take very good care of it, and it kept growing and growing and producing more and more zucchini.
In fact, at one point the plant looked like it was just about dead. Then half of it started to thrive again all on its own, and it started producing zucchinis again! It was a bumper crop for sure!
