North San Juan is NSJ, northern Gold Country, on the North Yuba River. Town is also known as Upper San Juan and no one can tell me if there is actually a South San Juan. Lots of rural residential w/ ranches back in here; private property backing to National Forest lands. Very curvy back roads, half of which are dirt. Snow is possible at this elevation, so take that into account when boondocking in that camper van during winter months.
