We arrive in Oakland at 2pm June 20 on a Sunday. We thought of driving to Sacramento for the rest of our day to see Old Sacramento and the governers mansion and maybe a river walk. After reading this forum, makes me wonder if we should just drive on to Lake Tahoe. I figure it will be at least 5pm before we get to Sacramento. Will there be anything left to do ? What time do the shops close on Sunday? Is the river pleasant for an evening walk or is it too hot?
