DALLAS--We all have that “tipping point” in life, that moment when circumstances converge to change our future direction forever. For graduating college senior Andrea Murdock in 1988, that point came as she was pursuing various options for post-college employment. On the one hand, she had already decided that she wanted to be a park ranger and had interviewed for a park ranger job with three different Army Corps of Engineers Districts—St. Louis, Huntington, and Mobile—at a job fair in El Paso. On the other, she had no real professional work history, and was considering joining the Peace Corps to get some solid experience on her resume prior to going for that federal government position.
