There's not usually a whole lot to talk about at the café in Big Stone City, after all its a community of just 600 people. But today, there will be plenty to talk about.

"Everybody is talking about it. a couple of guys have come in and are asking questions," said Margaret Kuefler.

Kuefler spent all of Wednesday night at the Big Stone Fire Department while firefighters were down the road, cleaning up a semi-trailer full of anhydrous ammonia. The truck flipped after colliding head on with a mini van on Highway 12.

"You run out there and there's lights all over, bright lights. Everybody is here, there…all over town," said Kuefler.

The threat of chemicals in the air prompted the evacuation of some 75 people near the site, including Les Iverson, who wasn't even home when the crash happened.

"I was out of town. When we came back from Ortonville they wouldn't let us on the highway," said Iverson.

He was allowed to go home for medication, but then, he had to spend the night with his daughter and son-in-law.

"We had no qualms about getting home. I just knew I would get home," said Iverson.

And by sunrise, he did. Thanks in part to the emergency crews and helpful volunteers like Margaret.

"You gotta pitch in and help when you can. I thought what the heck, I got coffee, I got hot chocolate, lets go out and do it," said Kuefler.

"By the time this thing is done, there will be five semis tipped over, this will be a big thing goin on here," said Iverson.

Anhydrous ammonia is a farm fertilizer than can cause health problems if people breathe it.

Officials say the leak was small and no residents were harmed.

The drivers of the semi and the van were treated for minor injuries.
