i have to see it first, lol....bakers a little town north of barstow, south of vegas, completly setup for the traveler, its a popular stop between vegas and LA, Orange and san bernadino counties, you will need to bring your own provisions to dumont among those should include your dirt tires(theres tons of desert riding in and around the sand dunes) and of course plenty of liquids, march should be around 65 degrees, could be 40 or 90 depending on mother nature, you will see lots of great desert riding coming and going to dumont, from vegas your looking at about a 2-3 hour drive depending on the traffic heading south on interstate 15.......
