From a Golf Course Superintendents Association of America (GCSAA) news release.
[CHARLES] SCHULZ DIED IN 2000, but his most famous cartoon character, Snoopy, lives on with a specially designed bunker on the 15th hole at Highland National Golf Course, the public course where Schulz caddied as a young boy and played golf throughout much of his life.
The character design was incorporated into the major course renovations that were completed in 2005.
"Charles Schulz was a huge figure in the St. Paul area and he loved golf," said Paul Miller, who collaborated on the course work with Garrett Gill.
"We wanted a way to honor his contributions to golf in the area, and Mrs. Schulz liked the idea. At first, we thought of doing a Snoopy-shaped pond, but the plans evolved into a Snoopy bunker. And it works to define the landing area of the hole."
The 15th hole is a 424-yard straightaway par-4, and the Snoopy bunker is clearly visible to traffic driving by on the neighborhood street.
