Answer: Three people who submitted answers.
I don’t know if these were tough and scared people off, or if some regulars didn’t get around to doing the puzzle. I like making these, so hopefully they were just too hard and it wasn’t a lack of interest.
1) Zones –> Danger zone, Strikezone, Endzone
2) Blue –> Powder blue, blueprints, feeling blue (down), bluegrass
3) Months –> March Hare, April Showers, Mae West
4) Rub-A-Dub-Dub –> The Butcher (Ed Gein), The Baker (Dusty Baker), The Candlestick Maker (John Bolles, the architect of Candlestick park)
4 – uberminz
1 – Randy, Beau

They were pretty hard. I think I could have gotten the fourth one, as I learned all of the facts I needed to get it; pretty clever.
