Yeah, you're probably right. Or maybe where I was a resident of when signed, or where we were headquartered when signed, or something along those lines. Depends on the wording of the agreement, which I don't have on hand.

I'm not overly concerned about it regardless, as should I leave it wouldn't be to a direct competitor (or likely anyone that could possibly benefit from my industry-specific knowledge) - it'd be somewhere completely out of our industry. And if they want to make an issue over someone as small as me, then I'll just find a new line of work for a few years. There's no way they could claim a "training investment" or "trade secret protection" if I was a programmer and left to become a carpenter or a roughneck or somesuch.

No, the law goes according to the headquarters of the purchasing public company. If they are headquartered in Cali, and you're in Colorado then your contract is according to Cali law. Also, Non-competes are non-enforceable in Cali - just FYI. However this is different from the trade secret situation.
