+1 on Engine 2 Diet books/videos
+1 on 1ofthem's eatery suggestions. I would add Arlos for burgers and mac&cheese. And Counter Culture is amazing.

Also,for learning the theory and science of veganism, Dr John McDougal MD is hard to beat. He has a website and tons of youtubes.
Last I looked Austin has several plant-based MDs.

I know 2 providers who kayak. Shoot me a PM if interested.

Enjoy
