I remember the days when little kids carried back packs to & from school. Now it seems everyone who is traveling, especially men, are carrying these back packs. Even men in their 60s are carrying back packs. What in the world are they carrying around. By the way we are now in Ireland & have been traveling for 59 days. Neither my wife nor I have these back packs & I certainly wouldn't be caught dead wearing those awful "fanny" packs. What is with men & their back packs. Some sort of security blanket; just like Linus in Peanuts?
