I'm not intending to hijack your thread, Scooter, but something I've occasionally wondered is relevant while we're discussing moonlanding sites.
Were the insides of any larger craters ever considered as landing sites, and if so, why were they rejected?
It seems to me that some of the newer, deeper impact craters in the mountains may have provided good samples of bedrock, if somewhat shattered. However, they may have been less interesting for some other geological reason of which I'm unaware. Perhaps not providing the variety that, say, Taurus-Littrow did.
