Cory,
I have to second (or third...) what others are saying. When you're at Bandon, just play! Frankly, you could spend all day on the practice ground; it's that much fun. I'm sure there are better practice areas out there, but I haven't seen one.
Jeff:
I know this reeks of "personal opinion," but you must play the Sheep Ranch. There is a chance that it is going away, and I think you'd hate to look back and say you missed it when you had a chance to play it.
I'll try to post some photos of some of the holes on Trails that Ed and Nyk mentioned. These are a couple of years old, and I'm a rank amateur...
First, a look at the par 3 5th, from the tee:
The 5th green. Try to take the time to have a putting contest...
Here's a look from short and right of the par 4 15th...
A picture of the par 3 17th, from the tee. If your match is still on, anything can happen here!
And then here are a few photos of the Sheep Ranch. You may not get a day like this in the winter, but you could spend all day on this ground, and still want more...
