And finally

Thanks to Dave for suggesting I write the blog to record the trip. It will greatly assist my ailing memory and I hope his students weren't too scornful! Hope those of you that read it enjoyed it.
My final observation is the contrast between the richer nations we visited and the poorer. The friendly Fijians who welcomed everyone to their country with a musical bula and waved you off with a melancholy farewell song at the airport. Both parents actually play with their children and men waving at you with machetes don't arouse any fear as they chop wood and collect coconuts by shinning up (unfenced) trees.
Contrast with LA where airport security is intrusive barrier to entry, where some of the richest people in the world (with their dogs in polo neck sweaters) drive by numerous beggars on the street and sleeping rough near the beach (the most we saw anywhere).
We left our footprints on the beach in Fiji and our fingerprints at the airport in LA!
You didn't think you would get away without a bit of politics did you? Bye
