The work done at Onwentsia made it one of the most fun courses on the North Shore (strong words I know). It's also one of the least populated courses in the District. Three groups on Saturday morning is often a lot. At their monthly men's guest days (of which I have had the privilege of playing many), I think they waive the guest fee and you pay for your guests' lunch -- it used to work out to about $75 per guest. Imagine doing that at any other club in the Chicago District (except for maybe a place like Old Elm or Shore Acres). The place would be mobbed.
I used to get on at Skokie in an annual Rotary outing, but that's gone by the wayside. Caddied for a friend at a Senior Am qualifier 2 or 3 years ago. The Prichard renovation is very nice. The fairway bunkers are extremely penal -- hit one and you're wedging out. There's a stone memorializing Sarazen's birdie on 18 to defeat Bobby Jones (and 1 other?) in whatever year their Open was. . .
