Mostar

Great bridge and terrible, river stone steps!
Hey, I've got a touch of wifi here in Copa, so happy to read of your adventures and all that history you're learning--good show! I loved Mostar (oh, that hauntingly beautiful, live call to prayer) and was there a bit after the bridge was rebuilt, when there were no hourly jumpers. However, I'm rather shocked that there were so many tourists there in September--I fear for your lives in Dubrovnik! Will it be another Prague?

Further travels
I'd love it if you'd return to Bolivia to join me here! However, I understand the hassle of distances--so annoying that they've not perfected teleporting yet! Then, you'll see airlines in your transport museums. However, a bit closer to you are Romania, which I've heard is gorgeous, Bulgaria, etc. I was heading there once from Budapest when the Danube flooded, cutting off all eastward travel, but it does seem affordable and exotic. Great that you've perfected early morning exploration to avoid the crowds; liners have become the scourge of travelers. I'm staying a couple of weeks in Copa since I have wifi and my own bathroom with a toilet seat and hot water--woo hoo!
