i was pretty optimistic starting out but hit a couple of road blocks along the way. I had a 5 hour layover in La Paz Bolivia that cost me $135. for a Bolivia visa.US cash. I started to argue, but visions of midnight express flashed through my brain. At Asuncion Paraguay they dinged me for $160. US $. My "book" said no visa needed for Paraguay. It's after midnight, they want 30 to 40 $ to get to town, I have no hotel reservation, I spent the night at the airport......I've slept in worse places. Day break take a 20$ cab ride to the bus station. Good timing/luck my bus was leaving in 5 minutes to Ciudid del Este......which was close to where I was going. I was beat, slept and this morning got a bus to Foz do Iguazu. Hope to visit the falls tomorrow, will pass along pictures.
