I just wished there were more people interested in captive breeding them in the US.
When I lived in North Dakota, Tiger Salamanders seemed to be everywhere. Since I've been living in WV and Maryland many years now - I've never seen them. Then I was reminded why after looking at their distribution map. The Eastern Tiger Salamander is confined mostly to the Southern coastal region. Tigers are way more visible and animated - it's not even close - Tigers win.
What part did you live in? I grew up in Bismarck, and Burleigh county may or may not have tigers from the distribution maps I've looked at (I never had any luck finding them there). But whenever I went to my grandparents' in Devil's Lake, I'd always find a ton of melanosticum and diaboli, and there are some who say there are tigrinum in the area as well.
