This is mbroblack's TrustRating, which is based on both the number of reviews mbroblack has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful mbroblack has been to the Kudzu community.
Some good deals can be found here, but the course gets a lot of play, so conditions are spotty. There have been a recent rash of on course robberies, so be alert. Average layout and a slow play place at times.
