Question about Uprights?

[SWFLguy]

In CNY lot of intersectional games, sectional play-offs, and state
play offs are in the Syracuse Carrier Dome. The goal posts were
always considered "legal" for those games. For a while we used
imaginary hash marks, but finally and wisely used the field markings
for ball placement.
I worked about 25 games there over the years and I'll tell you,
it was a pleasure to be able to work indoors in November in CNY !!
Anyone who saw last weeks D-2 Colgate game played in a driving
snowstorm while Syracuse U played Notre Dame in the dome can
appreciate what i'm saying !
