If I am going to hike the Smokey Mountains then I need to pick out a back pack that will work for me. I read the article Easy Packing on the website Biking Back Packer. And it gave some really good advice. One  thing was not to take the backpack without trying it out first. You do want to be sure that you won't have problems carrying it. So if you are thinking about hiking you may want to go to Biking Back Packer and read about picking a back pack. You will find some really great advice. Plus they have other information  that could come in helpful if you are going hiking.
