I’ve just spent four days in Costa Rica, which is of course far too little. Costa Rica is Central America’s most popular travel destination, and you can definitely feel the difference - there are noticeably more tourists there, especially Americans.

Hello everyone. I’m now in San Francisco. I’ve spent the past few days at a conference in San Jose, where I gave a presentation on Monday to quite a number of researchers from all over the world. Fortunately, it went well, and I received positive feedback from several researchers who were interested in collaborating with us.
