Glad to see this thread up RAZR .. this is for sure the greatest 2 day ride ever. I grew up with this race in the 70's and rode the dual sport version last year on my GSA, some hard ways some easy ways, but went all the way. Rode to Palmdale the morning of start and rode home from Vegas after.
The best roll chart tip I got was to cut each days roll at the lunch stop (or in half). This makes it much easier to use as it doesn't bunch up or bind at beginning or end. Last year's GPS tracks were dead on though!
Can't wait to go again this year
