The wind set it off once. And we sprinted over there. But there was no fish.

We went on the Internet and checked out the Guinness World Records site. There was no record for tip-ups.

Why did we name it Big Bertha? I don't know. Because it's big. Everything big gets named Big Bertha.

We said, why don't we build a really big tip-up, and use that spring?

We had one guy offer us $75 for it. Maybe we'll go into business.
