He's been to those schools before.
He's been to KU just a week ago, too: "Late night at the Phog". Maybe he's going to KU because it's on his own dime, and it's easier to get to Lawrence. IMHO it speaks volumes for him to visit KU two weekends in a row.
I read this earlier from a KU site before he decided to visit KU again instead of Kentucky and Duke:
Marques Bolden, a 6-10 senior forward from DeSoto (Texas) High School, who is ranked No. 16 nationally by Rivals.com, tells Jayhawkslant.com his weekend visit to KU “was great. I would say that the visit went much better than I expected going into the visit.”
Bolden has visited KU, Kentucky and Duke. He is pondering returning to Kentucky on Friday and Duke on Saturday for their season-opening hoops celebrations. He will visit Oklahoma on Oct. 23.
