We played a round today, it took us around 6 1/2 hours to finish the game... too much I would say. In a Wednesday, the marshal was trying to push the pace, but a fivesome was killing the pace of all. The course is nice, the sound of the highway beside it is monstrous. We couldn't concentrate the entire game because of the constant rumbling, which at the end it got us both in a bad mood. Some fairways are under repair so its awful to shoot from bare dirt not even yellow grass. In general, I wouldn't recommend traveling more than 15 minutes to play here, but if your drive is 15 minutes or less, then it's fine, wear some headphones the entire game and you might even enjoy it...

What a great course, the first 9 holes are challenging, the back 9 not as much. But it's still lots of fun. I went to play monday, (President's day) with a couple friends the pace was slow, (obviously) but we had a blast. The course is in really good condition, it is not an easy course, but it is not a horror movie course either. It is very enjoyable, play it smart most of the holes are tricky, at they seem easy, but calculate your distance and turns.
About the food I had a hotdog and a Sandwich which was great, but my only concern was that if they were serving food over the bar, I would have wished if they had a bar with onions, tomatoes, relish pickles all that stuff, instead they have a really small thingy with ketchup, mustard and mayo, all in little packs.

As for the rest I am thinking into becoming a member of their club if there is one ;)
