"The water," said Jill Featherwolf of Appleton, who is staying at the Bagley Rapids Campground with her friend David Kampen.

"I used to camp here a lot. So I wanted to show Jill the area," Kampen added.

But just down Highway 64, another marijuana growing operation on national forest property was broken up. That's not driving campers away but some are uneasy.

"I think the DNR has to step it up and check around these trails," said Al Champeau of Kaukauna, who who is also camping at Bagley Rapids Campground with his wife, Janice, and family.

Past marijuana growing operations have left their scars ranging from downed trees to deep planting holes to concerns about potential chemical damages.

"They come in with chemicals. They cut down trees. they just destroy the area they're planting in. I think without any concerns," David Kampen said.

The U.S. Forest Service has stepped up efforts to let sportsmen know about marijuana growing on national forest lands. And those efforts appear to be paying off.

"The last three marijuana sites that we have found over the past three summers have all been because of tips we've got from people out hunting and now fishing," said Suzanne Flory, Public Affairs Officer for the Chequamegon-Nicloet National Forest.

U.S. Forest Service officials recommend that anyone coming across signs of camping, gardening or cultivation in non-recreation areas of any national forest should leave the area quietly and quickly and report their findings to police or rangers.
