The real message of the flowers
Lee's purpose in publishing the picture (he's even more private than I am about his life outside of business) is how he found that technology has helped him to do what he loves longer than he otherwise could.
He has a watering system for his various gardens that would put a truck mount engineering design to shame, has his flower and vegetable beds planted in raised gardens, and uses a variety of tools and machines to compensate for the aches and pains of nearly 8 decades and fibromyalgia.
He draws the comparison to truck mounts over heavy portables, ergonomically well thought out tools, and
glides of course when it comes to actual cleaning. He also draws comparisons to how computer technology and the internet have made marketing and management more effective with less effort for those who are limited by "Budget and Time", as he is by neuromuscular disease and time.
That is the real message of the flowers.
