If you are looking for possible guests to bring onto a podcast or episode, how about Logan Broadbent and/or his father, Gary Broadbent. They are from Canton, OH and boomerang experts. Gary has given talks all over the world, including NASA on the aerodynamics of boomerangs. Much of the science used in boomerangs are the same in flight.

Logan has also competed twice in American Ninja Warrior (including the one filmed in Cleveland). Here's Logan's promo video for ANW 2017 https://youtu.be/Qp2_3p3hpaw

Here is a short video with Gary: https://youtu.be/WkWMBGAZBBU

Just a thought.

Have a great day!
