Did you go to any nature preserves? I'd love to go somewhere we can check out wild animals but i'm really skeptical about how 'wild' they are. We're avoiding anything called an 'animal park' or something similar but I'm not sure about places where you tour and just try to spot elephants and whatnot.
Also, I got some great info from this thread: viewtopic.php?f=14&t=3063&hilit=india
but since it's 2 years old I thought there might be some new info on the scene.
