Paul:
I haven't been able to find anything on North Shore Acres in some brief research on the web and my WI golf books. The old, funky, Depression-era course in Kenosha is Petrifying Springs, with some blind holes and some interesting use of the terrain. I've never seen PS credited to anyone, although it has hallmarks of some of the nearby Bendelow courses; he did a lot of work in this area. I don't think PS has any links to Langford; PS has pretty small greens, fairly tight playing corridors (it was carved for the most part out of a heavily forested park), and not the kind of bold features found at L/M courses. PS to be honest is probably closer to Lawsonia neighbor Tuscambia, a Bendelow, than anything else.
Will do some more research and post again if I find anything.
