Walking is Free

Walking is Free. I have noticed in guidebooks they always list some activity you can do for free. I am in Buenos Aires,Argentina at the moment.  This is the second time ive been here,and I have yet to go to a museum or paid event here.  Just riding the subway here is endlessly interesting  Like all cities,the different neighborhoods all have there own charecter. San Telmo has awesome grafitti and musicians playing in the street. Palermo has real nice modern malls. This is all to me living art. You can experience it - for free- by just walking around - or a cheap subway ticket --- so enjoy!
