Pros
It's a large stable company with lots of facilities nation-wide. There are many experienced people working there that can teach you every facet of the industry, so when you move on you have some experience.
Cons
No potential for growth. Severe case of 'Good ol boys' syndrome. Nepotism in the corporate HQ is rampant. Most managerial hires are from outside the company rather than promoting from within. Stifling PC culture. Anyone except outside sales are treated as a liability, no matter what their contribution to the company. I once saved Allen over $100k per year and barely got an attaboy, let alone anything else. Women and minorities are relegated to only work in Accounting, IT, or if they happen to be attractive they can make it in the product line.
