Ryan, current plan is to do the drive from Auburn to the winery, drink wine, and then head home.
Car is currently hung up, waiting for some parts to cure an axle seal leak, but should be good to go in time.
Your route up is something like the route I led three years ago (before you joined the group, I think). We went Placerville - Pollock Pines - Mormon Emigrant Trail - 88 - 89. We were slowed a bit on 88 with some construction stops and then Terry Nuckels had to show off his one-arm-tied-behind-the-back roadside clutch cable change, but it just made the challenge of reaching Tahoe under the power of a lawnmower engine all the more rewarding.
Cheers!
