Spain is a beauty you can never miss especially in summer. We visited Barcelona in July. Hot weather, crowded streets, populated beach, and cold sangria. That sums up summer in Spain. Even though we went for a wedding, we managed to do the touristy things.
I still remember as a kid i loved to travel from one city to other using three different types of transportation in India. In those days there were no metros or mono rails, not even direct local trains. You would have to take a bus from a bus stop outside the town, which will take you to nearest train station (few miles away). The journeys were long but the amount of people you meet and interact with on these journeys was an experience in itself.
