The tractors returned to Norris High School Tuesday.

For the rural campus near Firth, where the tentacles of urban growth are creeping closer and closer, it was a chance to celebrate its agricultural roots once again — if only for a few hours on the last day of school.

Along with row upon row of cars, 10 John Deere tractors pulled into the parking lots before the first bell rang Tuesday morning.

There had been some concern that the usual morning traffic — nearly 2,000 students from kindergarten through 12th grade share the 68th Street and Princeton Road campus — might be congested by the slow-moving, orange-triangled tractors.

But there was no disruption of traffic — and no traffic tickets were issued, rumors notwithstanding.

“The kids said that years ago the FFA kids drove their tractors to school on the last day of school,” said high school Principal John Skretta.

“That’s a demonstration of their pride in community, and our belief that even though we’re in such close proximity to Lincoln, we are still an agricultural community at heart. That’s what drives us and that’s our history.”

When the final bell of the year sounded, all but the tractor drivers fled for the summer. Skretta kept the tractor operators behind, just long enough to give the SUVs and buses a head start.

Then the tractors, too, headed  slowly down the roads, to their rural-residential, small-town and agricultural homes. School days over. Long days in the fields just begun.
