Judy and I will be there for breakfast. Will plan to leave the house by 8:15 and should be there by seating time.
Just a couple route ideas to expand on Mike's SPECULATED ROUTE. Instead of getting off 80 at the first Auburn exit, (a half mile after getting on 80 from the Ophir Rd on ramp), consider going up 80 three more exits to the Lincoln Ave. exit. Make a left on Lincoln at the end of the offramp, then a right onto Foresthill Road at the signal. A couple miles past the Foresthill bridge, make a RIGHT down to the confluence, where we make a left across the bridge at the bottom onto 193 to Cool. Much less traffic, great roads, maybe a mile or two longer, and doesn't take you through the stop and go part of Auburn in a group.
IF we're heading through Placerville via 49 to 50 west or via 49 through Gold Hill, or taking Lotus Road west out of Coloma, I think I'll return (with or without group) along Green Valley Road to Folsom (Lotus turns into it, as does Ray Lawyer Rd. and it skirts the northern side of El Dorado Hills). It's a great 2 lane rural country road that will take you back to Folsom Rd or the intersection of Greenback and Auburn Folsom Rd at the Cliff House Restaurant overlooking the river. I'm gonna be taking Auburn Folsom Rd back to Auburn from there, but for anyone heading back toward 80, it's one way to do it (via Greenback or Madison). If you want to ride Green Valley Road toward Folsom (instead of riding west on 50) and need to get back on 50 west, you make a left on Folsom Rd. when I go right, and it's maybe 2 miles or so to the on ramp onto 50 west.
FWIW
