Wide-open middle! So cool to see the three stair-stacked acrosses (HIT THE BRICKS atop SPACE TOURISTS atop PHONE SERVICE), with so many long down answers running through it. The grid breathes so well; the solving flow so pretty, so many ways to get into each section.

Love the pairing of HIT THE BRICKS and SPACE TOURISTS. Talk about getting out of town! I wasn't familiar with THE MECHANIC, but BRIMSTONE, NOISEMAKERS, CLASS ACT, DOG PARKS = such good usage of those long down slots.
CLASS ACT and DOG PARKS particularly shine — not because they're better than other entries, but because these corners often leave unfulfilled potential on the table within this kind of stair-stacked design. Peter does almost equally well in the opposite corner, with PITFALL / SHOO AWAY / PONYTAIL, even a TOY CAR to boot. A stair-stacked set of acrosses can make these corners inflexible and a bit blah to ugly, but not today.
Peter's grids typically are so snazzy and ultra-clean, that AWAG, THORO (do people actually use this?) and even IOC stood out a bit. They'd be virtually ignorable for most anyone else, but Peter has set an incredibly high bar for himself.
I don't mind a double dose of THE in THE MECHANIC and HIT THE BRICKS — it's such a common filler word — but getting a third in THE JONESES felt like too much. Maybe it would have been different if it had been with a shorter entry like THE FED or THE UN, but …
Peter did a great job of incorporating some rare letters in the south, that J and X worked in so smoothly. Usually, a tiny region's job is to be ignorable and not stand out with crossword glue but to get some JIM Kirk, TOXIN, even RATTY and YAY ME makes that corner a real asset to the puzzle.
It's so tough to achieve both sizzling and smooth in a wide-open 68-word grid like this. PHONE SERVICE didn't do much for me, nor OMELETTES, nor SHOO AWAY. Might not seem like too much wastage, but those take up some prime real estate. Still, I'm in agreement with Peter — well executed overall.
