Darn it all, Pat beat me to it. I had a similar experience with Keller when I was a young pup newly out on his own.
I was actually at one of the Minneapolis munis, Francis A. Gross Golf Course (I believe it's currently referred to as Gross National) for my first round after moving to the Twin Cities. While waiting to tee off, a beautiful spring day turned nasty in the form of a good ol' midwestern gully washer. I held out hope that I would eventually get out (I did not) and headed into the club house to grab a drink and a quick bite.
I was sitting by myself, but overheard the drenched threesome at the table next to me talking about Big Ten sports, notably Indiana basketball. As a Hoosier, I injected myself into their conversation and introduced myself. The conversation predictably turned to local course recommendations as I was brand new to the area. The two younger members of the threesome were offering up the country club for a day options in the area (Rush Creek, Edinburgh USA, the newly opened TPC Twin Cities). The older gentleman with them, who was a paired single, said through a mouthful of hot dog, "play Keller". The two younger guys resided just west of Mnpls and hadn't even heard of Keller, which is in a neighborhood just north of St. Paul. Afterwards I thanked them for all of their recommendations and filed them away for later use.
The following weekend the weather was lousy, but playable. I took the older gentleman up on his Keller suggestion and absolutely fell in love with the old place for all of the reasons Pat mentioned above. Amid all of the typical trappings of municipal golf were the existence of a great historical relevance and some dynamite golf holes. I also got the impression that those that called this their home course were extremely proud and protective of it.
What made the biggest impression on me though was that this was my first round in a new, distant place far removed from my parents and family. I was on my own now. I was still very young, but I felt an ownership of the moment that brought with it a sense of being a "grown-up" that I hadn't experienced before.
I know it's kind of a mushy story, but most golf stories are, and Keller made a real impression on me. I'm glad it did.
