Played Thunderbird yesterday a course I had played about 18 months ago and haven't played since. It was greatly encouraging to see the difference in my score (11 strokes) since the last time I played it.
Thunderbird is in a largely dry wash basin so it's very open and many of the holes are less than 300 feet. Even with little terrain and natural obstacles to work with the course designers did a good job making it a challenge. Many of the baskets are placed on either side of the wash on the sloping edge and the tee box parallel to the road so while you're teeing off on flat ground the fairway is pitched roughly 25 degrees so there are bound to be some wicked bounces, skips and slides. Particularly in the summer when the grass is all dead an it's only sand. Add in the man made obstacles of culverts and guardrails. I need to get back out there and take some more pictures. My favorite hole is number 2 where you tee off on the far side of the overpass, throw through the tunnel to the basket on the far side.
For a course that is by and large open it's a lot of fun and can punish you if you get over confident.
