On a past overland trip to Colorado, we had a bear try getting into our cooler. We left the coolers outside the Jeeps overnight. I have seen anti bear food vaults, and understand the idea. My question is, do we need to empty our refrigerators that are in the vehicles too?
Hiking, backpacking, and car camping in bear country for quite a few years now. The reason bears, and what I should say is these are specific bears, get and break into cars is they have had human food before. They smell it and yearn for it! They will do anything they can to get to that scent. (Breaking into cars, houses, tents, coolers....etc.) This behavior unfortunately leads to bears being killed because they will encounter people and be aggressive instead of skittish. Now living in Colorado it has been very annoying seeing people not read up on bear safety (I'm glad you are reaching out though!) and causing these bears to learn a behavior that is not natural for them. This then harms every other visitor to bear country. The examples above like Sequioa are great reminders of what happens when it gets out of control and humans do not do their part.
Now for the things to do!
- Cook a decent distance away from camp (we try to cook about 200-300 feet from camp when backpacking, car camping we cook right next to the car)
- When done cooking ensure camp is cleaned and no food scraps, fat drippings (Beverage cans are great for storage), or anything human related (anything that goes in or on a human) is packed away in a trash bag in the car. Water containers and tables can be kept out as long as you didn't splatter the sides of everything with food.
- Coolers should stay in the car if possible. If not then ensure it is bear rated and you understand how it is bear rated. (Yeti coolers are only bear rated if you use the pad locks on them) If you are backpacking try and use a Bear Vault and not a bear hanging system. Yes the bear hang works but small bears will still climb and know how to pull the strings down. Bears are extremely astute and figure stuff out over time. Best story I read was the bears in Yosemite after they introduced and mandated the use of Bear Vaults, the bears over the year associated the canisters with struggle and if they saw them in camp they would just walk away.
- Know where you are camping and understand what animals you will/could encounter.
For backup if all else above has failed and the bear is very aggressive we have bear spray and one other device that is last resort. But the best thing you can do is keep a clean camp and do not have anything scented outside in the open.
