Thanks to all who expressed concern and offered helpful hints. My son is out of Egypt and moved on to Budapest for a couple of weeks. You can see some of his photographs and story on a more or less blog he has at: http://theregoesmybus.com Since he was using the Leicas and using film and exposed about 30 rolls the bulk of his images are yet to be developed and scanned and printed (if they get printed at all!). For a time he photographed for a local newspaper and was seen after by "minders" (bodyguards?). The ones on the above site are iPhone photographs. Andy
