We have lived on the south end for about 23 yrs. I agree with Travlin Man, not a lot of traffic on the beach. An occassional bicycle, but no golf carts go by. Most of the beach front houses are far enough away from the main road that it remains very quiet. While we do use our cistern most of the time, it is definitly very nice to have city water as a back up during dry season or if you have guests who like to take epic showers.
The town board has paved the road just past Victoria House and it makes driving to town much better during heavy rains. I have gone over the bridge on rainy days and find it really jarring. Being able to have things delivered or just running to a grocery for milk is also a plus on the South end. We have many resturants within easy walking distance as well. The North end also has wonderful resturants of course. A lot depends on what you want in your life style, but sometime "convenience" can be a god send in Paradise.
