I've heard of sightings in the past few years, but not many, and nothing earth shaking. I don't think too many people fish for them on Chatfield. I've put at least one solid day into hunting tigers on Chatfield without seeing anything last year. It'd be nice to hear some more people fishing it for tigers and see what comes. My opinion is that they've died, escaped, or there's just too much other food for them and they're just not interested.
