So my wife, who homeschools our two children, came up with an idea to form a "Daring & Dangerous Club" for homeschooled kids (inspired by my two enjoying The Daring Book for Girls and The Dangerous Book for Boys). The idea is to do things with them that kids don't do much anymore in today's over-protective world.
Tonight, for our first meeting, I took a few kids (tween age mostly) to a local cave (Pompey's Cave). The cave involved a trip down a 12 foot ladder and walking through a stream bed (with one 5 foot rock climb and a short belly crawl). They did great. We got wet and muddy and got to hike back to the cars in the dark.
Next month, I'll be teaching them gun safety and we'll be target shooting with BB gun rifles and pellet pistols (they're too young yet for regular pistol shooting but could probably handle a .22 rifle - we'll see how it goes).
