I agree too. There aren't enough nights where bears will be a problem. You can ask at NPS and NFS offices about recent bear activity in the area. If a bear box is available, use it. If not, hang your smellies (food and toiletries) far from your tent. Even if you don't hang it well enough, it will be far enough from your tent that all the bear will get is your stuff and not you. If other campers are in the area and they have vehicles, you can ask if you can put your smellies in their vehicle for the night. If there are no bear boxes, but there are bear-proof trash cans, then put your smellies in the trash can, underneath the trash bag.
When I did the TransAm, I used bear boxes in Grand Teton, Yellowstone and the Beaverhead Deerlodge National Forest (Montana). I hung my smellies in the Clearwater National Forest (Idaho). Those were the only five nights of the whole trip where bears were a concern. Much of the time you will spend overnight in a town, where bears are pretty rare.
