Just want to make you aware of a neat thing the National Park Service recently launched - a service called Find Your Park, which is celebrating the centennial of the NPS (in 2016) and wants everyone to get involved in finding your local national park, enjoying it, and helping others to find and enjoy their parks, too.
As you know, I am a great fan of our local open space recreation areas, and local/state parks, and also of the NPS. It's cheap to visit them, you usually learn an awful lot about history, native peoples, and native plants and animals, plus you get to be outdoors in nature with your family, away from computers and phones and all the other distractions of daily life. The more time we spend looking at our devices, the more we have to carve out time to be away from them. I truly believe this.
As John Muir said, "Everybody needs beauty as well as bread, places to play in and pray in, where Nature may heal and cheer and give strength to body and soul alike."
