I'll throw one out: Geology!
Why you might ask? Well you said you did like science. Most current geologists are older, 50+ actually, and will soon be retiring. Add that with the fact that many people do not major in geology plus the ever more environmentally concious society and you get big money! Geology is a broad field and you can specialize in hydrology, oceanography, geophysics, etc etc. A lot of my friends in the department are graduating with just their BS in Geology and getting entry level positions in the high 50s, low 60s. Another friend of mine went to school for 2 more years for his masters, 70k plus starting out. Not bad to play with rocks and such. And the oppurtunites to start your own buisness, such as a consultant, are wide open, thats where the big money rolls in.
