Roche is a magical place. Benja and I thought it was one of the most realistic builds we have ever seen in Second Life. It reminded me of some forgotten rural place in Northern California off San Pablo Bay, on the way from San Francisco to Sacramento-- although it could be just about anywhere. The interior of the homes and shops is breathtaking, especially the Japanese Bakery near the train station when you first arrive.
Here is the official description of Roche from the SL Destination Guide:
A squawking radio calls you in from the coast. Get a free bicycle from the dispenser, then ride across this pastoral island, where touches of modernity meet a dreamy-eyed past. Don't be afraid to go off the beaten path and visit some of the buildings in the area.
