David S Day 18

 4/6. 

1. Chicago :(, D12. So close. I recognized Happy Days and knew that it was in the Midwest and on the water, but I didn’t know the actual city.
2. Joyce :(, D23. Nope!
3. Croatia :), D20. Gimme. I’m realizing people might put Italy thinking it’s the Italian peninsula (along with San Marino and Vatican City) and get this right. 
4. Methane :), D11. No real way to get this except to know it. Though the fact that marsh gas can explode may help. 
5. Sitting vice president :), D02. Was able to figure this out in a few seconds. 
6. Pass line :), D31. I’ve played my share of craps.
