No higher ed or trade schools. Hooker Co. has a population of 745 (as of 2002) and only one town in the county. Mullen has a population of about 500 now. 1 in 4 residents in Hooker Co. are over 65 years old. Something of interest: andhills Golf Course a private golf club designed by Ben Crenshaw is located in Southern Hooker Co. An LLC based in Denver CO. has purchased some land 10 miles west of Sandhills Golf Course with plans for another private golf course. Current plans call for two 18 hole courses, one designed by Jack Nicholas. Not bad for such a remote, sparsely populated county (just one of the reasons they want golf courses here, the others are the sand and layout of the rolling hills and the wind - all very similar to original Scottish links courses.)
