A memorial flag ceremony was held this morning in Omaha to mark the one-year anniversary of a deadly tornado that hit a western Iowa boy scout camp, where four Boy Scouts died and 48 others were injured.

In the last year, volunteers and workers rebuilt the Camp Ranger's home, built a new tornado shelter and cleaned up a lot of the mess the tornado left behind.

One year after 4 boy scouts were killed at the Little Sioux Scout Ranch one of their greatest and newest additions is their first tornado shelter which can withstand winds exceeding 200 miles an hour.

Boy Scouts enjoyed a peaceful day with a light rain at the ranch, quite different than Reservation Director Denny Deters saw 1 year ago, "Overwhelming, buildings destroyed, trees just every which way. That part of it right there much less the kids themselves was kind of a double hit on me."

Within those kids Rex Gochenour saw heroes, "The efforts they went through that night. The way they responded. Yeah, we're proud of them. I guess there's no other word to say but we're real proud of them."

One year later both of Rex and Denny have things that will remind them of the destruction that was one year ago. "We have our flag here at the entrance of camp that was bent over during the tornado and we've kept it at an angle and we've proudly flown the flag all year except the first month and today to see it go back down to half staff, it was pretty emotional," said Denny.

Some emotions will never go away, even as they try their hardest to rebuild the camp that took four of their own. "The front end of this camp was just a disaster area, but thanks to thousands and thousands of volunteers that have come up here, it's amazing what a difference a year makes," said Denny. Rex added, "we're gonna get there, but we've got a long ways to go yet."
