I found this article that has him mention with a paragraph in it
Two of the top 2010 players in the Midwest were also in town on Saturday. Leading the way was Harrison Barnes, a 6-foot-5 wing player from Ames. While most people think that Barnes is a lock for Iowa State, and that could very well end up being true, the fact that he came to Iowa City on his own dime to check out the Hawkeyes is certainly an indication of some level of interest.
Having seen Barnes play this summer, it will be a big surprise if he doesn't end up being a Top 50 prospect in the 2010 class. He has offers from Iowa and Iowa State and this week he is expecting Wisconsin and Purdue to take a closer look as they visit Ames High School.
here is a link to the rest of the article. but I posted all the info about barnes
