Oldstyle点评：加州湾区附近有一处知名的景点—纳帕山谷，那里有非常多的当地酒庄开放参观，非常适合品尝当地佳酿，值得家庭或三五好友一起体验。

sculptor点评：旧金山艺术宫是一座纪念性建筑，最初是为 1915 年巴拿马太平洋国际博览会建造的，用于展示艺术作品。 它是世博会中唯一在现场幸存下来的结构。 艺术宫最突出的建筑是一个 49 米高的开放式圆形大厅，一侧被泻湖包围，另一侧毗邻一个大型弧形展览中心，由柱廊与泻湖隔开，很有特色。

sculptor点评：旧金山铛铛车是一种少见的地面缆车，拉车的铁缆是在铁轨中间的地底下，所以车上没有马达和喇叭，要靠手拉的叮当开路。幸好铛铛车跑不快，还是旧金山老城区的地标。

co****ean点评：Visiting the Powerhouse was our favorite activity on the day we spent in Folsom. It's in a scenic location on the banks of the American River, and close enough to walk to the historic downtown where there are some other small museums and restaurants. The visitor center is modern and attractive with easy-to-understand displays that explain how hydroelectric power is generated and show the history of the facility. Admission is free (donations accepted) but there is a fee to park (free parking available nearby to the south). The old equipment in the powerhouse was fascinating - it felt like we stepped back in time - and the docents were friendly and very knowledgeable. Wheelchair access on the grounds was okay with some assistance; there were some unpaved areas and grades. Note that this attraction is only open noon to 4 pm and is closed Monday and Tuesday.
