Several years ago I booked a divetrip to Utila,
Honduras... knowing the island was behind the times I asked the diveshop on the island what the kids would like to have... After a couple of days I received a reply... A WORLD GLOBE.
After personally carrying it on the airflight and placing it in an overhead bin which bearly let it fit the "world" and I arrived on the Island of Utila. A week after I left I received a nice
email from the diveshop that it was decided that the library would have it so all the students and adults could see and inspect new countries...
Later trips I brought "flash cards" and color pencils; rulers and compasses; anything we take for granted but oh so hard to come by in a third world country or island..
