Well, they were only 2 days late. After a re-routing through Heathrow, Nairobi, and Burundi, they are now safe and sound in Kigali, sans luggage. The guitar made it (carry-on), so we have already had several impromptu concerts.
Kenyan Airlines has promised to deliver the luggage when it arrives. Trouble is, we don't have an address (no one really has addresses in Rwanda). We have instructed them to send it to:
Mzungus (white people), near Merez petrol station, Nyamirambo. The Merez petrol station part is kind of redundant, but good security as pretty much everyone knows where it is.
