You could also drive to Sacramento and ride the bike trail from Sacramento State college to Folsom and back. No cars, flat. Great food available around the Sac State area, coffee and really great food at Bella Bru (Arden & Fair Oaks Blvd.) about 7 miles up the trail. Good eats and drink in old town Folsom. Total ride would be about 32-34 miles.
