The Teeter-Totter works great! It’s very challenging to know how a new idea is going to work. I recognized the challenge: Trees will need to be removed. Then an opportunity: Trees can be used as beams. Then another challenge: I need to get the tree up on top of the posts. Then another opportunity: The tree is really close to the height I need it right where is stands. Next challenge: I need an apparatus that can connect the dots… The development of Grainchek as a useful tool has a similar pattern of challenge and opportunity!
