I searched Google.com on "Guy Graves" +zoo +Louisville Here is a bibliography but I don't know how old it is so you may need to search for more recent things: http://www.fs.fed.us/r2/nebraska/gpng/literature/litferret.html http://leader.louisville.edu/edtl/brown/EDTP%20653%20syllabi.pdf mentions him in relation to "conservation center", "black footed ferret project" So, back to Google Results 1 - 10 of about 335 for "Louisville Zoo" +"Conservation Center". (0.24 seconds) and one of the top ones is http://www.louisvillezoo.org/conservation/stories/con-ferrets.htm which should easily get you some contact info There! Now you also know a LOT about easy searching which should help you find things in the future. Now you can fish for yourself very easily. Another tip: if you select the "cached" version in Google then the key words will be highlighted, allowing you to skim to the sections needed, plus sometimes it gets people into articles which are no longer available or may be otherwise inaccessible. Searching is EASY once a person gets used to the tricks enough that they become habitual. If he has moved to a different location then asking someone at this zoo should help you find that zoo, foundation, project, university, etc. unless he has retired in which case you can ask if they can forward a letter with your contact info while also considering approaching other experts (which makes sense, anyway, if you have not already done that). --- Clover, I LOVE your nursery rhymes. You bring marvelous poetic imagery into them. > Last night I felt her in the air > A Yogi girl who wasn't there > She wasn't there again today > I wish that she'd come back and stay completely entrapped me. --- Rebecca answered a question for me about BIG! Now I know why the evidence disappeared that the Earth was once flat but that ferrets in flying saucers pulled it into a globe like puffing a layered flatbread by pulling on it with giant bungee cords. I'll bet they had fake space/sea monsters they put near the edges beforehand to protect mariners, too. Hey, a ferret isn't the mascot of the Massachusetts Colonial Navy just because of rodent protection! Shhhhh! That's a secret! Bill, you cad, you!
