Going from east to west, the entrance to Milwaukee Country Club is about a 1/4-mile from the entrance to Brown Deer Golf Course (site of the former Milwaukee GMO PGA tour stop), which is about three or four city blocks from the entrance to Tripoli CC (Bendelow), which is about three to four blocks from the entrance of the Wisconsin Club golf course (formerly Brynwood CC, originally a William Diddel design). As the crow flies, those four courses are separated by about two miles.
Addendum: The well-under-the-radar Big Foot CC in Walworth County, WI (maybe Bendelow's best 18 holes in Wisconsin), is about a 1/4-mile from the criminally unknown Country Club Estates (maybe the best 9-hole course in Wisconsin; another Bendelow), which itself is about a half-mile from the Killian-Nugent Abbey Springs, near the western edge of Lake Geneva.
