Some trivia from my analysis of the geographic distribution of disc golf courses and population. [Data from the PDGA Course directory as of 9/10/2009 and 2000 US Census.]
The place in North America with the highest density of disc golf targets around it is at Trinity Links in Lockport, IL. [This is the place that maximizes the number of targets, divided by the distance to those targets.]
The course with the fewest other targets around is Kapalua Adventures in Lahaina, HI (even if you count Poli Poli).
Taking into account player preferences, the best location would be at Earl W. Brewer Park in Grand Rapids, MI. [Here is an example to illustrate the difference between the best location and highest density: Location A has an 18-hole course next door, a second 18-hole course five miles away, and a third 18-hole course ten miles away. Location B has six 9-hole courses, each five miles away. Both locations have the same Target Density, but most players would prefer to live at Location A.]
However, taking into account player behavior, AND the Availability of the courses, the place with the highest disc golf Service Level is at Mason County Park in Ludington, MI. [Availability reflects how crowded a course is. A player will play a course with an Availability of 50% only half as much as a similar course with an Availability of 100%. Availability is calculated based on the surrounding population, and number of other courses around.]
However-er, when the weather is taken into account, Lovers Lane Park in Bowling Green, KY comes out as the best place for a disc golfer to live. [Player activity decreases when weather is too hot or too cold, or daylight hours are too short. Bowling Green isn't as cold as Ludington, and there aren't that many days when it is too hot.]
The place that produces the lowest Service Levels (while still being next to a course) is Montiel Park DGC in San Marcos, CA. [This is mostly due to the huge population, but also from lack of other courses in the area.]
The place where excess population does the most to reduce Service Levels is around La Mirada Regional Park in La Mirada, CA.
The course where population has the least impact on Service Levels (in the U.S. – I don't have population data for Canada) is at King Salmon Park in King Salmon, AK.
The place with the lowest average Availability of nearby courses is at Kendall Indian Hammocks Park in Kendall, FL. [Players in this area would play more than five times as often if the courses weren't crowded.]
