Spending two years and tens of thousands of dollars to get a degree in a field you have never experienced before is a recipe for unhappiness. Nobody here can tell you what program you should apply for - you need to figure that out for yourself.
I am pursuing an MS in outdoor recreation, focusing on park interpretation. I didn't enroll in this program until after I spent six months as a recreation outreach intern with the U.S. Forest Service's Alaska Regional Office in Juneau, and then five months as a field ranger at the Tongass National Forest's Mendenhall Glacier Visitor Center. Then I knew this was a career I was interested in pursuing and, through a student-to-career program, could find permanent employment in.
