This is the traditional method of launching hang gliders.   Historically  the training hill allows you to get off the ground just high enough to learn the flight characteristics while being only a few feet off the ground.   It is here that some people click into the flying mindset and forever more walk the earth looking up with their eyes and heart.   Then when the pilot becomes more skilled, they go to mountains for the thrill of high altitude flying.   This is the absolute best way to go sight seeing throughout the world.   The senses and emotions you  feel are beyond description.  In this area there are some nice hills and mountains to fly from.
