Anthony,
It is a very interesting and good golf course. Although I am a low handicapper, it should be fun for the mid if you play the right tees. There are some very wide fairway areas and lots of waste bunkers, there should be plenty of pics on this website or other places online.
Is it worth the trip? Well I would say yes and no. I would not come for just one round at Chambers Bay, but if you can squeze another course or two into your plans, then I think it is well worth it. Try researching the Home Course, Gold Mountain, Courses at New Castle, etc.
Chambers is a fairly unique course and hard to compare to others. Lots of "waste areas," good bunkering, and highly contoured greens. We are starting to transition into the fall up here so be prepared for all cool weather conditions with possibly lingering rain in you come in the next couple of months.
Is it worthy of a major? Yes, I think so. It is very challenging and I am curious to see how they set the mowing patterns for the Open, but it will be sure to be a challenge for the best players in the game. Grass conditions are improving and should continue to improve during the fall.
Hope that helps. Enjoy the round.
