Yup, re Sand. I went on a church field trip to MV when I was a teen. I had my Ross 10-spd and flew over the handlebars when i drifted off the road and into some deep sand. Survived with only a gashed knee! :-)
Rubel's isn't printed or made anymore so might be hard to find a map of those except for overstock...
Check out Mad Martha's for ice cream!
