Individual or team play would both work pretty well. If teams were used, the members of each team would rotate throws one by one, each using the same frisbee from where it landed on the previous throw.
A throw must be done from a standing position with one foot always touching the ground. The pivot foot for each throw must be in the position where the frisbee was when it came to rest on the previous throw. A throw is holed when the frisbee comes into contact with the cup/hole. Use a tap-in if you are close enough to the cup: if you can touch the cup with the frisbee without moving your pivot foot, it will be considered a holed throw.
We will follow the same rules of golf if a frisbee is thrown out of bounds. A frisbee is deemed out of bounds if it leaves the park/school grounds, or if it lands on top of a building (this would stink very much due to retrieval), or if it gets stuck in an area from which the player cannot retrieve it using his hand.
Location would be the most difficult problem to solve, such that it would be nice if each "hole" had its own little quirk that you had to manuever through or past. Basically so that each hole didn't feel the same. I'll use Calhoun here for an example (which might work), but I think we'd probably have to scout a park like Eisenhower or Newbridge for a better course if frolf got voted in as an event.
1. Tee off from the shotput area. Cup is the boys locker room door on the north side of the school. Nice straightforward first hole. Par 3.
2. Tee off from in front of the boy locker room door. Cup is the tree near the tennis courts where the shotput area used to be. Nice big dogleg left and then big straightaway with an out of bounds area hugging the left side of the fairway. Par 5.
3. Tee off from the tree. Cup is the handball wall. The high fence is the big issue but the wall is the biggest cup on the course. Par 4.
4. Tee off from the other side of the fence where the handball wall is, on the baseball field. Cup is the home plate of the baseball field. Another straightforward hole but with a very small cup. Par 4.
5. Tee off from home plate. Cup is the northern upright (just hit any part of it) of the football field. Need to fade hard left to get onto the football field with your tee shot. Par 3.
6. Tee off from in front of the northern upright. Cup is throwing the disc between the southern uprights. Makes for a possible eagle hole. Par 4.
7. Tee off from in front of the southern upright. Cup is the center basketball backboard on the western side of the basketball courts. Possible out of bounds (top of the school) if you overshoot backboard. Par 4.
8. Tee off from underneath the center basketball backboard on the western side of the basketball courts. Cup is the home plate of the girls softball field. Getting the disc over the fence on the first throw limits its distance. This is coupled with another very small cup. Par 5.
9. Tee off from home plate of the girls softball field. Cup is either door of the equipment garage. Straightforward, easy hole with a big cup. With a wind going north, could result in a hole-in-one. Par 3.
Total Par = 35 throws
