Barcelona is one of my favorite cities in the world. To have been to the Catalan jewel is to love it. No other city is like it. It's vibrant, bohemian, beautiful and one of the worlds great walking cities. From the beaches to Camp Nou it has something for everyone to enjoy. But the heart of the city is Las Ramblas. I've walked and sat on this great pedestrian thoroughfare for countless hours since my first visit in 1998 people watching, drinking sangria, trying not to get robbed, and exploring all the little side streets, plazas and alleys that culminate on this beautiful street. What happened yesterday was a tragedy but it will never stop Barcelona's heart from beating. Have you been to Barcelona?
