As chance would have it, I am in traffic while I write about today's traffic-themed puzzle. Who knows what such a coincidence will yield? Let's start with the revealer RIGHTONRED, or "Traffic go-ahead that should be followed four times in this puzzle." The instructions are clear: when you get to the word [RED] in a down answer, you take a right at the intersection with the Across answer and enter the rest of the answer so that the complete Down answer appears in something of an L shape, CHECKE[RED]FLAG and CU[RED]MEAT are two examples. When you look at the across answers, it e-merges that they also work on their own, as independent answer - always an attraction. :)
I pretty much sped right through this one, with only one bump in the road where I tried GOESbroke before "Gomer Pyle's outfit: Abbr." (USMC) straightened me out and I realized the answer was GOESUNDER. There were some fun stops along the way including "Play by play job?" (STAGEACTOR), "A little cracked" (AJAR), "Early man?" (BOY), and my favorite "Refuse to pick up the bill?" (VETO) - ha! I also enjoyed THRUMS, SPLOTCH, and DUNNED along the way.
I apologize for the late review today - sometimes real life takes a toll. Exit.
