Well, I'm coming from a biased view, but we definitely have lots of women in traditionally male fields! My sorority, Sigma Alpha, was formed to promote women in agriculture. Thus, we have a very high percentage of women in what you might classify as technical majors: agricultural engineering, animal science, plant & soil science, horticulture, pre-vet, forestry, biology, landscape architecture, etc. The remaining members are mostly agricultural economics, agricultural communications, agricultural education, etc. majors (mostly B.S. degrees but somewhat fewer "technical" courses). I would say that we also attract a fair number of women to Greek life who otherwise might shy away from it.
