My son and I are planning a DS ride as a father/son adventure when he graduates from High School (May, 2009). We have decided that we would like to do an unsupported ride to the Grand Canyon and back. We are both plated. He's on a WR250 (that should be a 290 by the time we head out) and I'm on a WR444. We both have a range of about 110-120 miles between gas stops, but can carry a bit extra. While we can ride on the pavement, we would prefer to keep this ride as much on the dirt as possible. We can get from our house in Palmdale (Ca) to State Line, Laughlin, or Needles pretty easily and have ridden all of the portions we plan to link together to get there. What we need is route recommendations (or even better GPS tracks!) to get from either State Line/Henderson/vegas, Laughlin or Needles to the Grand Canyon. I posted this up on the SouthWest forum a couple of weeks ago and haven't gotten much help...any would be appreciate.
