Mark O'Shea is great, love the dude. He is all about the research and study of reptiles, not making it a publicity arena on TV. I also do like Jeff Corwin. I have yet to see anything he say to be incorrect or negative to herpetology. Both in my eyes do a fair job at pushing conservation and respect for our scaly friends. All others seem to drizzle nonsence for ratings.
By the way, Micheal Moore is right....another great dude.
