I want small class sizes, a public school, lots of field work, and research opportunities. I want to eventually get a Ph.D. and travel the world, finding missing data on these creatures, educating and informing the public on them, and helping conservation efforts. I would prefer to hear from students on the recieving-end of these classes. Thank you. My email is closetrockfan@yahoo.com
