I believe Brad's book says Ross did work on 3 holes at Allegheny, a true gem of a course.
I think also that they have been doing some restorative work (sorry, Mike Young
) under the astute guidance of Hanse Design, but I could be wrong on that one.
I'll be in the area in 3 weeks and am looking for some recommendations.
This has been covered in pretty heavy detail on here, it's in the archives. I'll try to see if I can find some later.
To sum up: Burgh private great, Burgh public not so great.
