... on the Amateur "Ham" Radio air, that is. Rotarian and ham radio operator (callsign KA5GIL) Gil Jones did an updated classification talk today based on his ham radio hobby and the National Park System.
The American Radio Relay League (ARRL, the national association for Amateur Radio™) has teamed up with the National Park System (NPS) to celebrate the 100th anniversary of the founding of the NPS.
Throughout 2016, Amateur Radio will be helping the National Park Service celebrate their 100th anniversary. Hams from across the country will activate NPS units, promote the National Park Service and showcase Amateur Radio to the public. ("NPOTA," 2016)
The local Ham club, Highland Lakes Amateur Radio Club, "activated" the Lyndon B. Johnson National Historical Park in March on two different weekends, giving operators a chance to talk to President Johnson's "Western White House" as it was known. Gil mentioned that there were 483 NPS units eligible to be activated by Hams. "Activation" means that a ham radio operator is communicating from an NPS unit. So far, Gil has "worked" (i.e. communicated with) 34 units across the U.S.A.

The original notion of a "national park" is credited to George Catlin (1796-1872), a self-taught artist who worried about the westward expansion and the effect on Indian civilization, wildlife and wilderness. (Smith, n.d.)  
Yosemite, now a national park was originally a California state park, having been given to the state by Congress in 1864. In 1872 Congress estatablished Yellowstone National Park in the territories of Montana and Wyoming. That began a worldwide national park movement where today more than 100 nations contain some 1,200 national parks or equivalent preserves. ("History (U.S. National Park Service)," n.d.). Our NPS includes 20 categories including battlefields, military parks, historical parks, national lakeshores, national recreation areas and more. But it was until 1916 when President Woodrow Wilson signed the legislation that the National Park System was officially created.
Of the parks Gil (given name "Guilford") contacted, the one most significant to him was the Guilford Courthouse National Military Park in North Carolina as his name came via an ancestor's participation in the Battle of the Guilford Courthouse, March 15, 1781. 
The largest, most hotly-contested battle of the Revolutionary War's Southern Campaign was fought at the small North Carolina backcountry hamlet of Guilford Courthouse. The battle proved to be the highwater mark of British military operations in the Revolutionary War. ("Guilford Courthouse National Military Park (U.S. National Park Service)," n.d.)
General Nathaniel Greene met the British General Cornwallis head-to-head there and so decimated their forces and supplies that the Brits fled to New York, but rather than resupplying, they wound up surrendering because the French Armada had cut off the British supply ships. Thus, the Guilford Courthouse battle can be said to have led to the end of the Revolutionary War although technically we lost the battle. 
This flag is the "Guilford Courthouse" flag of which Gil has a replica hanging in his mediation office.
Gil's message about the National Park System was that it is a wonderful system with great beauty and history, and ought to be seen and supported.
Gil spoke briefly also on how he came to be Justice of the Peace for Burnet County Precinct 4 upon the early retirement of Judge Ed Cutchin. He explained how the County Commissioners and Judge were looking for someone to appoint who was not going to run for the position, and who was dumb enough not to say "no."  He figures his name came up unanimously.  smiley
