A course called Pittsburg G&CC in Pittsburg, CA is listed in The Life and Work of Dr. Alister Mackenzie as having 9 holes designed by the Doctor. I tried to unsuccessfully tried to find out more but by doing a quick google search and GCA search. I think the course is now called Delta View GC. The only reference to Mackenzie on the course's website is found in the description of the 18th hole. It seems that Robert Muir Graves must have added an additional nine hole.
Has anyone seen/walked/played this course? Does any Mackenzie remain? I'm sure I can't be the only one who would be interested in seeing pictures or hearing opinions.
