^Agreed. Renny Gold's a bear for sure. Different courses can take their toll in different ways: Extreme elevation, lots of long holes, extremely challenging and unforgiving, can be brutally hot, or just a mental beat-down.
Haven't played any on ski slopes, like
Hickory Hills , but I imagine they can be quite exhausting.
Of those I've played, these stick out:
Idlewild: pretty much wore me out in a well balanced fashion, beat me up a little in every way on a 100 degree day.
Toboggan: not quite a ski slope, but not too far from that. After all, it
is on a toboggan run: combo of brutal rough and hard to find shade for stretches can really take a toll over and 8800' of serious and continuous elevation changes.
Ponds of Lakeshore: not a demanding course...
except when you make the mistake of playing the 4th of July in 97 degree heat on a course that has no shade.
Nevin: If the finnesse game is not your idea of fun, this could be one of the longest, least enjoyable rounds you play.
