I have a bag problem. It's rivaled only by my shoes and my jacket problems. I collect the things. I throw away too much money every year on the quest for the perfect bag for travel, or every day, or evening, or conventions. I have four different bags just for lugging my camera equipment around. But I only have one backpack in regular use (the other is from high school and covered in X-Files quotes). It's specifically a backpack for cameras, and unless I need to haul a multitude of lenses around it never leaves my closet.
