Don't mean to butt in guys but why go thru Evansville to get to Mt.Vernon? Instead of getting off at I-164 continure West on I-64 to the New Harmony exit. Thats Indiana 69. Exit South thru New Harmony and continue to Mt.Vernon. At the square in Mt.Vernon Hwy 69 will turn West and run with Ind 62. A couple of miles out of Mt.Vernon Hwy 69 will cut off to the South and 62 will continue West. Go South on 69 until you come to Hovey. It's several miles........
