What map are you using "Z"???Follow I-15south from wellesville and turn onto 28,follow south on 28 till junction with 89,go south to junction with 9 and 89(left to Kanab,Right to Zion)your choice Zion or Kanab.In the am do as Becky suggests.Take 89A south and re-connect with 89 at Bitter Springs,then south to Flagstaff and on to Prescott.Hwy 64 is scenic but unnecessary miles and you will be tired.We will have time on saturday for group ride along the rim of the canyon.Just sayin'
