The best way to see a country is to simply walk through it. Being one with the surroundings surpasses all other experiences affording a full immersions into the sights, sounds, and smells. And since walking can be a little on the slower end, I tend to run. I ran almost every day when I was in Buenos Aires, an easy four to six miles before dinner along the Puerto Madero canal. I commit to running in every country I visit.
So have at it, run fast, run slow, just get out there and explore!
