http://www.vrbo.com/vacation-rentals/usa/california/central-valley#5841 Link is too houses in discovery bay rented out by owners. Which is nice since most of them have boat lifts and near town (i.e. good restruants, movie threaters, etc all within 20 min). Plus the two houses below are only 8 minutes to fast water (in disco bay it can be up to 30 mins of 5mph zone). Also there are 4 great sloughs all over a mile long and up to 5 miles long all within 20 min of each other on the water. Lost isle (google it..lol..not for the family though) is also about 25-20 min from disco bay.
cheers, dc
This one is a very nice house.
