1. Plan your route in advance.As for me I'm trying to pick a route that day that has me playing 6 18 hole courses in one day with some of my disc golf buddies.
2. Aim for an east to west route to maximize daylight.
3. Do it on a weekday (as opposed to a weekend) if you can swing it.
4. Hit notoriously busy courses at off peak hours.
5. Minimize drive time between courses so you have more time to play.
6. Have all food, water and other supplies packed the night before.
7. Get a good night's sleep the night before.
8. Realize that some of the things in this list might be at odds with others.
9. Try to document your experience (photos, video, scorecards, live tweets, etc.), so you can share it with others and perhaps encourage them to do something similar, or join you next year. If you do want to envision an event one day, that's how you plant the seed.
