Ken, Thank you for the info. Helps a lot. I suspect I will have the 18-135 on for most of the time but plan to bring the 70-300 for on the boat and a 50 1.4 for dusk shots.

Cheron , I am sure all will be willing to share photos. Lets talk Pat M into doing a book for NILE like she did for ROAR 2. It was fabulous.
