Seriously? Your mind isn't made up already? I don't blame you, it is a pretty big decision. But Colorado is fantastic! I myself just transferred to CU Boulder this semester and I am in the ENVD program. Most of the teachers I have had this first semester have been pretty cool. The coursework is interesting and somewhat challenging. I like the program alot. The campus is wonderful and Colorado is sooo much friendlier than any other state I've been to. Way more layed back and slower pace of life too. I recommend you come visit the campus before you make your decision though.
Take yourself to higher places.
