Driver window
Tee height, face loft, and path as a 3-D room. Bragg Saturday wind gets a note on the margin so the drawing does not pretend it was still air.
Fayetteville, North Carolina · Sandhills geometry lab
The window is three lines, not a slogan
D-Plane Fit draws the plane that actually owns the ball: club path through impact, face normal, and the spin axis that sits perpendicular to both. Cape Fear dew thickens that window. Fort Bragg weekenders bring a crosswind they forget about until the chalkboard shows the curve arriving late. Catalog talk waits until the drawing exists.
Why Hay Street
Humidity is a co-author
A drawing made in dry mountain air lies on a July afternoon beside the Cape Fear. Sidespin lives longer here. A fade that “should” fall at 160 yards still hangs at 185 because the air is thick and the window was never measured in that air. We note dew point on the sheet the way a surveyor notes a benchmark.
Indoor mats flatten the third line. Pine-straw lies at Highland and the municipal tracks around town tilt it. We run both when the argument needs it — the chalkboard is the same, the lie is not.
Three panes we actually draw
A window, a lattice, a short pane
Iron lattice
Each iron is a pane in one wall. If the 7-iron window leans left and the 5-iron leans right, that is a bag problem, not a “commit to the fade” pep talk.
Wedge pane
Partial shots rotate the window. Pine-straw and wet sand around Fayetteville punish a pane that only existed on a mat at full swing.

Radar, then chalk
Numbers hit the board as lines, not as a printout you never look at. Face and path get their own color. The third line is the argument.
-
Head and shaft as furniture
We move loft, lie, and shaft only after the window is stable enough to blame the furniture. A new head cannot invent a plane you never drew.

Photo of the board
You leave with the chalkboard, the dew-point note, and which pane still needs a second visit. Nothing is a mystery PDF.
Session shape
We draw before we shop
Hay Street is a brick storefront, Suite 5, not a big-box hitting bay. Cole still starts every new golfer by putting three lines on the board — even the ones who arrive with a yardage book and a favorite shaft forum thread. If the window is crooked, shopping is a delay tactic.
Heard on Hay Street
What weekenders actually notice
“I thought the slice was the path. Cole drew the face as the first wall of the room. The fade I wanted was already in the window; the club was opening the door the wrong way.”
“July humidity here makes a curve hang. They wrote the dew point on my sheet. I stopped blaming a shaft I bought in Colorado.”
“Pine-straw 5-wood was a different pane than the mat. They made me hit both before anyone touched loft.”
