Goddamn I loved everything about Streamsong. HouTex's review is pretty spot on. The Black wasn't open when I played last August, so I can't comment there. I found the Blue to be hard, and somewhat goofy. Green set at weird angles, overly-sloped sections of greens for no good reason, strange visuals off of some teeboxes. That's not to say there aren't AMAZING holes out there - #3 sticks with me, as does the great par-3 over the water (signature hole). I found the Red to have the same links quirkiness as the Blue but played more fairly. Good shots were rewarded, bad shots were punished. Birdies were available, but not a given, even on the 5's. There's so much shot value out there it makes my head spin. Let's take 7, mid-length par5 back up the hill. Tee ball down the left shortens the hole considerably, but brings some bunkers and a long, dark, deep hazard (ie lake) into play. But it leaves you a straight away long iron into the green. Drive it out right a bit and you're still in the fairway, but playing over cross bunkers to get to the pin, and a back-left pin is completely hidden from you behind a big hill in the middle of the green. Lay up shots need to be precise due to that same hill (depending on hole location). Green is TINY, but lots and lots of flat putts mean you can make birdie with two (or three) good shots on the hole. Miss left, double Miss long, double. Miss short to a long pin, bogey. Just a fantastic fucking hole. They're all like that.
Go play. Stay out there at least one night, preferably two. Play in the morning, go take a dip in the pool and shower, get a beer or two. Go out in the late afternoon and bang some balls (you'll probably be the only one on the range, but they'll keep it open for you), then hit chips and pitches on the short game area. Wrap up the night with a bourbon or five. Get up early and do it again.
Heaven.
