Some places you do not have a choice- bear cans are required. Other places, you have to make the choice. After many years going around on this issue, I now take my Bearikade on most trips required or not. However, there are still a LOT of areas where you would not need a bear can, but if you end up in some of the more popular and well used places, you will eventually have to have one. If in grizzly country, also do not forget to take bear spray!
