Hmm...
We need to get 4 more (with one being Roads); they need 3 more (one of which is nighthawk).
We probably don't get two more turns, but we have to assume we'll get one more. Which means either:
• a clue for 4 (seems unlikely given the previous clues)
• a clue of 3 and we'll need to figure out this other Roads word.
• a clue of unlimited, meaning we'll have to take a random guess for at least 1 word and get the Roads clue.
Since we're unsure, I suggest we take the risk of guessing now and getting two shots at it.
If you agree, this is what you said previously:
I don't like nail, ship or switch. Ring is a possibility if that's another way to say beltway. Let's pass for now.
I agree that switch is not great and I'm not convinced on ring (though in addition to a beltway there are also rotaries). I still think it could be nail or ship, but not necessarily better than saturn.
I think if I had to choose, I'd go ship > saturn > nail > ring > switch
SO I'm ok with either ship or saturn this turn, and if it's wrong and we get another turn we can try the other next turn. (unless you prefer nail to ship)
