Has Anyone Had Experience With Wild Spots Foundation?

I have received an email from this group soliciting my participation in their group. I did not follow a link provided inthe message, but rather did a Google search and got to their website through this method. They seem like a cross between a scientific/enviornmental group and nature travel agency. Some of the photographic "opportunities" seem to be in a zoo of captive animals.

Deos anyone here have experience with this gorup? Are they just a travel agency or a legit environmental organization?

Thanks for your advice.
