Nick, you got a lot of us thinking over the last couple of years.
Mars has always surprised us. Every time we start thinking we have Mars figured out, the planet shows us that it is a unique planet with its own characteristics.
I think, with our growing data, we are getting a grip on Mars.
The hard thing for me, and others, is not to let my view of what I want Mars to be like interfere with the data coming in from Mars. That is one thing you taught me.
