Know anyone still stuck there? Do not travel alone. If hassled by

If anyone who reads this really is stuck in Egypt right now, it's probably important to mention that the h in that word isn't silent. It probably represents this sound http://en.wikipedia.org/wiki/Voiceless_pharyngeal_fricative or that one http://en.wikipedia.org/wiki/Voiceless_epiglottal_fricative . Sound files of both are accessible from here: http://hctv.humnet.ucla.edu/departments/linguistics/VowelsandConsonants/appendix/languages/agul/agul.html
