Take Highway 45 south out of Nampa, to Walter's Ferry. Cross over the Snake River. Just after you cross over the river, the road Y's. Go left. You're now traveling south on Highway 78. About a mile after the Y, you'll turn right on Upper Reynolds Creek Rd -- there will be a sign saying something to the effect of "Hemmingway OHV this way." Go down the road, past the 'cow farm' and to the OHV parking area. You can't miss it. There's a nice little hill climb right there at the lot, and you'll see an old XT550 flying around it.
