I know exactly what you mean about a good MDC job. It's hard. After I finished up school, I worked out at CERC (Columbia Environmental Research Center) for a couple years as a tech mostly radio tracking Silver and Bighead Carp on the Missouri River with the USGS and briefly with the USFWS. It was a dream job for a river rat like me, but had to keep deferring my student loans and was on a 3 month contract basis with little job security. A couple of my buddy's were working on there master's and had problems getting jobs too. One day out of the blue, I decided to go back and get an MBA in finance (with many pre-requisites) and now work in Saint Louis. I miss those days, but am paying off the loans now.
Again, thanks for the other info on the park zone
