Buenos Aires to Iberá

We headed out in the evening from Buenos Aires on our first overnight trip with a company called flechabus. They had a nice flat screen and techno pumping from the office where we bought the tickets leading us to believe that they may be pretty good. Not too long after the bus had departed we pulled over to the side of the road (half way through the crappy movie we were watching by the way, which is annoying when it´s some of the only entertainment for the night) because the electrical system was malfunctioning. Ahead of us on the side of the road was another bus from the same company that had a broken alternator. The guys on the bus were very nice though and 2-3 hours later we were switched to a new bus and on the road yet again. Most of this didn´t matter to us anyways because all it meant was that we would arrive at a more reasonable hour in Mercedes our destination en route to the Esteros del Iberá.
