The U.S. Forest Service recently put a ban on explosive targets for all the forests in Region One, that's northern Idaho, Western Montana, and part of the Dakota's.
Palouse District Forest Ranger Gary Kedish said exploding targets are a relatively new product, and sport shooters can buy kits that include all the chemicals required to make them.
"Very colorful, and very exciting," said Kedish. "The big issue with those is once those chemicals are mixed, they actually become an explosive and can cause wildfires."
Kedish said they've caused at least 16 wildfires in the western states over the last two years, and they can easily injure humans as well. If you're caught using an exploding target, you could be fined up to $5,000. Kedish said all campers need to remember to never leave a campfire unattended, and it's a good idea to bring a fire extinguisher on your camping trip just in case.
