Don't make it an issue.

Finally, try not to get too worked up about your age as you're moving through your job hunt. There will be discouraging moments. But, don't think of yourself as aged out — think of yourself as extremely qualified.

You have years of hands-on experience and tons of refined skills that you're bringing to the table. That's not a bad thing, so don't view it as one. If you don't make your age an issue throughout your search, chances are others won't either.
