I'm writing this entry from Java, my fourth Indonesian island. Some years ago Ann and I had the good fortune to visit Bali (#1) for a vacation, my project here has been primarily in north Sumatra (#2), and I did get to travel to Nias (#3) to check some radio installations. I'm now in Java (#4) to visit the IFRC headquarters in Jakarta and install a radio for the early warning system.
Checking Wikipedia I only have 17, 504 islands left to visit!! Wish me well ... only about 6,000 of the islands are inhabited so it may be a bit lonely.
And as an aside I'm now in the southern hemisphere having crossed the equator on the flight from Singapore last night.
