For those of you who weren't aware, there's still time to register for NASK, the Nord-Amerika Somera Kursaro, an excellent three-week Esperanto course in San Diego, California. Enjoy Southern California and learn Esperanto at the same time! There are scholarships available for those who can't afford to attend; you can find more information at the NASK website. Note that the courses are taught fully in Esperanto. You don't need to be at a high level to attend, but you shouldn't be a first-day beginner either.

You can earn US university credit for these courses, and your Esperanto will improve drastically, from using it for 3 weeks, solid.
