Can’t make the ride, but here are some ideas that you may want to consider. Saturday after Auburn take 49 south to 193. Take that to Georgetown then Wentworth Springs road to Ice House road to 50 to Mormon Emigrant trail to North South road to Omo Ranch road to Mt Aukum road to Plymouth and back on 49 to Jackson.
Sunday Morning take 88 east to 26 to West Point then Railroad Flat road to Sheep Ranch road to Murphys and there you will be back on 4.
There is food in Lake Alpine. I went there for lunch today. I liked it. There is also food in Markleeville at the Cutthroat Brewing co. I have not been there for a few years by I think that it is still good.
Let me know if you have any questions.
