I throw putters around the yard for practice. Between the back yard and front (and a little of the neighbor's yard) I can choose a variety of lines and elevations. The longest throw is about 220' uphill, with enough trees and bushes to make it interesting. I move the practice basket around to practice different lines.
My favorite practice throw involves hitting a gap between the house and a huge pin oak and then making a controlled turn downhill to land near the stop sign on the corner, with the road as OB. It's a fun shot forehand or backhand.
To practice with midranges or drivers I throw hyzers down the street, fading into the neighbor's front lawn. Fortunately all of my neighbors are pretty tolerant of (and, I suspect, entertained by) that fool throwing frisbees in the yard.
