David S Day 18

 4/6 today. 

1. North Korea South Korea :), D02. Gimme. Interesting accidental conservation area. 
2. Poseidon :), D12. Took me a minute, and then it was obvious. 
3. Montreal Canadiens :), D21. I don’t know much about hockey, but this is a quirk I’ve known about for a while. 
4. Double Dare :), D20. My favorite show for at least a year just under 40 years ago. 
5. Das boot :(, D31. I had nothing (reasonable) here. 
6. Water ducklings :(, D13. Something about this vaguely rang a bell, but not enough for me to get both words.
