Jay,
I played Entrada a few years ago. A small group of us flew in from Mpls/Chicago and played Entrada, , Sunbrook, Green Spring and Sky Mountain. That was just before the newer and better courses opened. Entrada was a lot of fun to play. Most of the holes were pretty solid and the setting is drop dead gorgeous. On the back 9 (15?) you come over a rise and all of a sudden your are playing in a lava field. The contrast of the lush green grass, black lava, and red hills is pretty spectacular. It's worth playing there just for the back 9. A few of the holes are a little tighter and trickier than they need to be. It would be fun to go back there and play these newer courses. St George was an easy place to stay.
