But why wouldn't the computer take your original planned route? Probably not
because it didn't recognize the fixes, but because of traffic flow reasons.
Same reason John does the PYE1 arrival over water.

I fly V3 which is the prefered. Leaving KLNA I open my flight plan with PBI.
Always get a few vectors east or west. Maybe 1 mile off shore. Then intercept
V3 and as filed.
