Lane Spaces

[BillyMac]

I've been watching this thread develop and have decided to participate. The question appears to be whether or not the "foot-plane rule" applies to the back "invisible" marked lane space boundary. Doesn't the red highlighted portion, below, answer that question? I don't understand the confusion. What am I missing?
A player occupying a marked lane space may not have either foot beyond the vertical plane of the outside edge of any lane boundary, or beyond the vertical plane of any edge of the space (2 inches by 36 inches) designated by a lane-space mark or beyond the vertical plane of any edge of the space (12 inches by 36 inches) designated by a neutral zone. A player shall position one foot near the outer edge of the free-throw lane line. The other foot may be positioned anywhere within the designated 36-inch lane space.

Look up LANE boundary.

Congratulations Billy, you made the same mistake I did in post #14.

I'm caught up on the word "any". Why doesn't it say "the" lane boundary? Is the NFHS referring to any boundaries along the lane, possibly including the lane line, the marked lines, the neutral zone, and the invisible boundary in the back of the marked lane space? Or, in the sentence that contains the word "any", is the NFHS only referring to the lane line boundary?
