Well organized and all the important things they got right — pre race info and packet pick-up, shuttles, course info and markings, organized start, water and aid stations, finish line water and fuel replacement even for the back of the pack.
My only negative is that just when the course starts getting pretty — (yes) vineyards and distant mountains and cows — instead of downtown streets past random houses — it is time for the Half marathoners to turn around. Definitely consider doing the full marathon to get the beautiful course.
