Midwest Tree Climbing

Mark Larson runs this destination that is centered around one massive, 5-story tall, 300 year old oak called "Goliath".  For $20 pp, kids aged 5-adult can be harnessed and taught how to scale this tree, and then climbers can try it for as long as they like.  The tree is fitted with a series of ropes that have special knots so you can use a combination of upper and lower body strength to scale up to the highest branches.  He got the idea from a course he took at Atlanta based Tree Climbers International.  Try tricks like the upside down "Batman", and he will also rescue you and bring you back to ground instantly.  The views and sounds at the top are amazing.  On the ground there's a basketball hoop, picnic tables and a grill, so your group can bring food and sports equipment along to make a day of your trek.
