Lost tall insulated travel tumbler with handle, lidded top and straw forgotten in a car on route from Al-Zarnooq (before Darwish Fish) to Lighthouse in Dahab. Poster remembered color as red but photo shows white to black gradient tumbler. Poster asked how to find it and if there is a drivers group. Update in post: item was recovered thanks to honesty of Dahab residents and driver Abu Hanin
