A candidate that wants to serve two high meeting volume boards at the same time flirt with failure. I have served different boards in several capacities and so continue to doubt the ability of even super-good and smart people to continue to think so little of their citizens that they will attempt to serve on two boards at the same time.
When meetings conflict , and they try but fail. Which meeting with they attend? They will go to one and ignore the other meeting. So they serve one board and ignore the other. One cannot be in two places at the same time.
