My wife & I will be in Florence in mid September. After spending two days there, we are renting a car and want to drive around Tuscany. We already have booked a hotel in Siena for four days and want to drive around to see the country side. We would like to do a one day trip to the Chianti region and the wine country, one day trip to the sea side, and still don't know what else we should be doing. If you have any suggestions, we would appreciate it very much.
