My non-compete says I can do no work I did with my ex-employer anywhere in US. Is it enforceable?

My non-compete states that I cannot do any of the work that I performed for my former employer (engineering), anywhere in the United States for the period of one year. I did not quit, I was laid off.

Economic conditions are such that transitioning out of thus area of work are nearly impossible for me.

I have not been given any trade secrets, no training outside of what is common knowledge in the profession, and have no pressent access to client lists. I do not plan to knowingly solicit business from past clients, and the client base for this business is common to everyone in the business, that is, most clients use a number of these businesses concurrently.

I plan to work outside of Illinois, 1000 miles distant. Although my former employer does business throughout the US, the new employer is mostly in a small region.
