Last year myself (drz400) and four others (kdx200,xr400,wr400,ktm300) started with the dual sport route. I led ,as I was the only one with a roll sheet holder. After getting off course a few times,we just stayed to the dirt roads. Most of these roads progress from maintained gravel, to jeep trail, to atv/snowmobile trail. The GPS got us back to Silver Lake when we started to get hungry (and thirsty). There we very few small bikes last year, but it looks like a much larger bunch this year. There is no lack of riding choices.
