One thing I haven't seen posted (for fear of redundancy!!) is a "bear bag" ...
I prefer the "rustic" campgrounds, so bear avoidance is good policy.
Not that you can really avoid them...they live there...But yes, you should do what you can not to attract them.
Camping with a group, a bear bag would be good policy.
I usually camp alone. Since I don't have to carry a lot of food and I want to travel light, I pack canned or sealed foods because they don't give off any yummy odors that might attract bears. This also saves me the trouble of a bear bag. When I'm done with my meal, I wrap up any trash in a plastic bag (another recommendation...bring a few along) and hike it off to the dumpsters (There are usually some bear-proof dumpsters at remote campgrounds) soon after. I most certainly do not leave any food debris laying around my campsite.
Funny, I just had a conversation with another rider/camper just yesterday, and he told me of a trip when another rider in their group left salt out, with the result that the group had to stay in their tents watching while a bear ransacked their supplies.
Last year, camping at Pine Creek Gorge, PA, late at night, something was sniffing around outside my tent...I thought it may be a bear but I didn't want to startle it by opening the tent to find out. The next morning I was told that law officials were called down to family campground in the next valley because the campers with a bad trash policy had attracted a group of bears.
Just a few weeks ago in the Shenandoah National Park, I found a bear watching me as I threw some trash into the dumpster. I ignored him and he toddled away. Other campers said he was one of several.
Black Bears usually don't want any trouble with people, but like many wild animals, they'll do almost anything for a snack.
As an aside, I don't bother with MRE's. They are expensive, and the size of the stiff packets take up the same amount of room as a can of ravioli and a 1/2 can of fruit. They are much lighter though, but that's not a big factor when it's my ride, not me, carrying the burden.
If you want a quick egg and bacon breakfast tho...Yeah, they're good for that. 8)
