ROANOKE, Va. -

Under those Friday Night Lights, no two teams are the same.

The fields they play on are all different too.

Like most fields, here at Glenvar they have good old bluegrass.

A few schools have artificial turf fields that cost hundreds of thousands of dollars.

My question tonight: which one gets the most bang for its buck?

They're all 120 yards long and 53.3 yards wide, but they're not all the same.

Take Northside High School and Athletic Director Butch Tyree.

For him, taking care of this field never stops.

"It's always something, it seems like, that we're replacing every year," he said.

His annual budget for this field: $15,000.

Tyree says it always seems like he's spending way more than that:

"We just spent $14,000 with some irrigation problems, leveling both sidelines and we just put 16-thousand square feet of sod on the two sidelines."

This season, Tyree's also had a problem with grub worms killing the grass among other things.

Across town in Salem, Scott Sampson really doesn't have those problems.

His biggest issue: "Snow. That's our only bigtime problem and even that we can remove and have a playable surface," he said.

Considering snow isn't a huge issue in September, Sampson admits his job is a little easier.

He does have plenty of field maintenance, but, "You know exactly what you have to do and when to do it. A grass field, you're pretty much, you have to do everything according to your weather," Sampson said.

These artificial fields are expensive, though.  On average, these fields cost nearly $720,000.

For an athletic director like Tyree, "I would by far think that would be a better overall situation as far as the money goes."

The reason why Tyree says it's better: Use.

Keep this in mind, all that money spent on maintaining real fields is just for game use.

Between soccer and football, Northside only uses that field around 30 times in a whole year.

For an artificial field, Scott Sampson told me in order to use it, all you have to do is be able to see the green, plastic grass.
