Hi Dr Bruce,
Thought you might like to have a look at some photos of West Sumbawa taken by a young Aussie guy Geoff Sims last year when he visited Sumbawa.
He posted the link to the photos on Lonely Planet Thorn Tree tonight. http://www.users.on.net/~simsg/travel/id-sumb.htm
Thanks for the link pamela, but the site is blocked by the company here. Maybe I can check them out next time I'm in bali.
