We have a few driving range only places, but they're just that - ranges. No bunkers, no short game, small practice greens. A few of the nicer semi-privates have improved options. Driving range, larger greens, some targets, maybe a bunker/chipping area, etc.
The truly nice ones are behind the high end country clubs that your daily golfer won't ever set foot on. I think as tdogg mentioned above, if the "average" golf course improved their practice facilities they'd probably find a decent influx of members. Many of us want to practice more than the ballstriking part of our game but the options may not be there.
