First, doubtful the Keen's are exiting. They have $33M shares and are likely selling a chunk to take advantage of what they've built. This is their baby and I don't see them running. JMHO. Second, my guess is you've quit buying dips because you, like most of us, see this doing nothing but rising.
Your view of the American Dream sounds kinda 1970s - 80s. Don't think Brandi is the stay at home watch the kids kinda girl. Being your own boss and spending time with your kids when you want is way better than being stuck with them ALLL DAAAYYY LOOOOONG. Don't see the Keens stepping out of the picture any time soon.
