The environmental engineering gig would have been a shift, as it has some construction management aspects and exists in the civil engineering world (meaning I would need to get a PE license). I'm trained well enough to do that job though, after a point all the engineering calculations and systems begin to look alike, regardless of discipline.

The job I'm leaning towards is consulting/contract work, more along the lines of product engineering and manufacturing. I'm a Mechanical Engineer and I have experience in that area, so it's a good fit. Also a much better location.
