YELLOWSTONE NATIONAL PARK -

Officials have yet to locate the bear that killed a man Wednesday morning at Yellowstone National Park; an uneasy thought for visitors hiking trails and camping overnight.

Today's fatal grizzly attack was the first one in Yellowstone in twenty-five years. Coming at the height of tourism season, the park is filled with visitors who hike the trails now knowing the dangers that are near.

"What happened today, we are a little more alert and try to be better prepared than we already are," said Michael Lauer, visiting the park with his family from Germany.

"If we had a planned hike we'd get the information form the Ranger first where the safest place would be and we'd approach it that way," said Frank Freyvogel, who was watching over a group of teens from Long Island, New York, "I definitely would not hike with one or two people off on a back trail."

Hikers make sure to take as many precautionary measures as possible, to ensure that they remain safe when in areas where grizzlies could be near.

"We stay on the main trails, we have people around us, we avoid too deep back country hikes, and in case we go off the beaten path, off the trail, we make some noise, clap our hands, talk to each other," Lauer said.

Freyvogel agrees, the Boy Scout leader goes over all safety procedures with his troop before they hit the trails.

"We stress on sticking together in groups, and we've gone over some of the procedures if we see a bear, so we stay close to the cars and the doors are open in the cars in case you have to get in quick, but no, I feel very comfortable."

While today's attack has left people cautious about what trails they hike on, it seems as though it hasn't deterred them from still enjoying their time in the park.
