Terri met Steve Irwin on Oct. 6, 1991. The Oregon native was visiting Australia with friends. "I went into this little reptile park, and Steve was doing the crocodile show, coincidentally ... I was absolutely floored. That was it. This man was a real-life hero. I fell then and there, love at first sight."

Despite the loss of her husband, Terri says she still feels blessed that she had him in her life. "I had romance like I didn't think existed anymore, a wonderful romance. He was passionate and determined and enthusiastic."

He had so much enthusiasm for life, at times, Terri says, it was hard to keep up with him. "There were so many things that made me crazy, like his desire to do everything now. He had a real sense of urgency with his life and no side view business plan. If you got plans, we'll do them now."

At Irwin's memorial service, it was said over and over again how "Steve changed the world." Terri says he changed the world by giving everyone a message. "If you can reach out and touch and love and be with wildlife, you will forever be changed and you will want to make the world a better place ... If we do nothing ... we're in trouble. And he did more than anybody. So I think we can all do something."
