I just read this thread now. Interesting discussion topic. Too bad GT_ME had to muck it up.
I agree that there is a danger to the profesion in splitting it up too much. I recall reading several articles, several years back, by NSPE and NCEES about trying to attract more engineers into licensing. I seem to recall that was one of their main justifications for adding the new specialties - just to get more members.
Also, speaking as someone who graduated as an ME, and moved into the "useless" field of environmental engineering (you can never go back!), I can say, with authority, that there is plenty of stuff in civil that an ME simply does not know, and it isn't that easy to learn. MEs are no better than Civils, no matter how much harder the subjects may seem during school. But then, with all his background in the real world, I figured GT_ME would have realized that by now.
Another interesting subject was the recent (last year?) article by NCEES about requiring more course work beyond the BS in order to qualify for licensing. 5 years seems like the figure they mentioned ... and I can agree to that, especially for civil engineers, whose work covers such a broad range of subjects. Broader than ME.
