We are planning our August vacation and have decided to stay a Friday night in Sioux Falls. As we have been reading the reviews, we have noticed others talking about a light show in the evening at the Falls, however we can't find any information on it. Can someone enghten us on this? Also we will be needing a hotel close by, any suggestions? Out party consists of disabled husband, myself and our small dog. Is there anywhere else we need to check out while in town?
