I tuned in to a documentary last night on discovery channel about the big bad creatures from the Amazon river, so I was waiting for an aro to show. It has anacondas, and a cayman getting attacked by an electric eel, then went into the electric eel wow! wish I could post a video of that, unbelievable. and NO ARO ever mentioned. We are legends in our own minds. So anyway, my Mom's a librarian and those DVD's and Videos can be requested by you at your library and most libraries will search and do an interlibrary loan even up to the library of congress. Should be free. Ask for the reference librarian. Mom knows more about where to find the answer to anything or has the research at her fingertips. You can go in and sit down at a inner library computer and search ond order yourself, even from home if you get the link. If the material is good, copy the isbn# and then you can order it online.
