I too have been trying to find someone in Alaska who breeds Dart frogs! I know that I can have them shipped up here during the Summer months, but it seems that I'm usually ready for them during the Winter months, When shipping is impossible.
Is your Vivarium set up yet. If so, any pictures?
If you do find a local breeder, please let me know and I'll do the same for you.
What kind of frogs are you looking for?
