everythings the same until you turn on hwy 448; once on 448 go to the third stop light you come to(about 3 miles) and turn left on hwy 79 go (about 5 miles on 79) and turn right on to hwy 144, stay on 144 til you go thru Payneville and then Andyville once past Andyville you will come to hwy 228 turn right on it and stay on it until you reach the boat ramp
