Complain, complain, complain, that's pretty much all my last post was. So here's another thing I love about Istanbul: the old city. I am just always bowled over by the amount of history to be found here, that people have been living in this area and sailing these waters for more than 2,500 years. I especially love taking the ferry from the Asian side to the European side (or the reverse) at sunset...you get a great view of Topkapi Palace and Aya Sofya, and everything always seems so calm and lovely from behind the ship's railing.
On this particular trip, I also saw for the first time some of the dolphins that travel through the Bosporus! I have heard conversationally a number of times that the dolphins had been nearly impossible to see in the last couple of years, mostly because of pollution, but that they're suddenly back, a sign that the Bosporus is cleaner. According to my trusty friend Google, it seems that they're also under threat due to overfishing in the Black and Marmara seas and noise from passing ships.
