No I am explaining how we will start out making these changes for
engineering reasons. How to follow a process that doesn't destabilize
and destroy what we already have. While your back-seat driving, asking
about detailed choices of side-roads 4 weeks from now on our road-trip
is not very productive when we're not even sure we'll be in the
country of those roads you want us to take – or if we will have
swapped the hummer for a jeep.
