Mrb, it goes like this:
1/19, Overnight in Miami. Next evening, down to Manaus, arrive late. Have a day on land, then get on a boat, chug around the Amazon for a few days.
Down to Iguazu Falls for a couple days, then over to Rio for a couple. Back through Houston on the night of 30th-31st.
If anyone's interested, I have a
blog over in Travel that I scribble in during my adventures.
