The train ride itself was an interesting experience. Although the distances are considerably greater on the train, it costs far less than the subte! $1.50 (pesos) gets you there, and the shopping and entertainment experience is unlike even the busiest day on the subway here in BsAs: We were entertained by a boy singing (in a beautiful voice, I might add) -- he was with his dad, who was on crutches; allegedly there were no siblings and no mother, just the two of them, as he announced before he began to sing. Then there was an Aboriginal pan flute and indigenous string instrument guy (also very talented), and a fellow blasting some horrible pop music out of a portable CD player (the CDs were for sale... sales, needless to say, were slim).
Once in Tigre, we wandered along the scenic route into the market area, where we met our friends and their two daughters at a cafe. After some more meandering, through the market, we stopped at the river to enjoy the view. A street dog had the same idea, and was leaned right up against the fence, watching the water intently.
On the way back to the train, we stopped for some waffles. Then it was time to catch the train home to our little corner of Buenos Aires, where the locals were getting ready to celebrate the first night of Carnaval!
