there are very few vets that treat reptiles, even here
I live in probably the most populated area on this continent, and I know of a total of three vets that will see herps, and one of them moved to Pennsyvania
I don't suppose the majority of them thinks of a herp specialization as a good investment; I'm sure for those who went that way, it's not what pays the rent, and they did it because they love the critters
