[Az-Geocaching] GPS 20 year anniversary

On Paul Harvey today he had a story how the GPS was invented 20 years ago and the first one was the size of a
microwave. Even though he did not mention GeoCaching, the article did mention how 100,000 are sold every month.
Amazing what has changed in 20 years.
