Joejoecor, best of luck. By leaving the PTO now, they are really doing you a favor. Even if you had started with a laidback Primary/SPE, the day would have ultimately come when you would have gotten people you had to work with like the ones you used to. At that point, you would have had 5 - 10 years working for the PTO, and nothing to show for it experience-wise when you left. As bad as the economy is right now, you are much better off getting out early. I have seen this sort of thing happen many, many times, and when people leave, they always ask why the did not leave sooner. With only 1 or 2 execeptions out of over 100 people I know with similar anecdotes, they were all exceptionally happy to have left. However, in some cases, they had stayed too long, which made it difficult, if not impossible, for them to find a new job.
Best of luck,
