My husband and I are in our 70s. We don't travel much anymore except to family weddings, etc. We like to go to the river house about once a month. We entertain at the house and eat out several times a week in Guernevile. In summer it is delightful to swim off our dock. We even had people swimming in early June last year. We love to read. Even in winter it is often warm enough out on the deck to read in the sunshine. That way we can get some vitamin D, catch up on our reading and watch the river activities. On cold days, it is cozy to read in front of the fireplace.
We often take the dogs (2) for walks on the beach at Monte Rio , in the local cemetary and in Armstrong Redwood Park.
Korbel Winery which you pass on River Road has a very nice tour which we take visitors to see.
Prior to purchasing Real Neato in 2006 we would rent a house at the river for a week every summer. Other trips we took were to Alaska, Peru. Kenya and Nepal.
We had always wanted a home with water view, so when this house came up for sale we "seized" it and did major remodeling to suite our taste for open space living. So I guess our motto would be carpe diem (seize the day)!.
