Cast iron pan has a hot spot

[chowdom]

I have a really nice big cast iron pan that once belonged to my father, I'd like to use it more often however it has a hot spot. I tried seasoning it but that has not fixed the problem. Can anything fix this problem or does it need to be tossed.
Thanks in advance

Howard McGee had an article in NYT about it.
