Hover your mouse over a marker for a course-name tooltip
One may link to a specific state/area on this page eg:
http://www.referential-integrity.com/DiscGolfCourseGmap/default.html?area=New%20Jersey

Get your Flickr photos onto this map by adding the following machine tags: gmdgc:pdgaid=[pdgacourseid], gmdgc:hole=[holenumber], gmdgc:suborder=[a number to sort within holenumber], or gmdgc:pre=[anything]. pdgaid will get the photo into the course's slideshow, the rest provides a sort in descending order as so: anything with a pre tag (to be used for map, sign, etc), hole number, suborder, and lastly anything with no other gmdgc:tags.
