...especially if you were actively looking for it and knew generally where to look.
In this respect, I guess we can agree to consider Riker's exclamation about the Moon looking refresheningly different in 2063 an unadulterated piece of bullshit.
Riker is trying to inspire Cochrane to see the benefits of an active space program and a bold new future that his stardrive is going to usher in. Thus, even if Lake Armstrong can only be seen when one is looking really actively, and perhaps only in illumination circumstances that don't really apply to First Contact Day, Riker would use it as an argument here.
