I've had to learn how to deal with all the normal travel challenges
like passports, currency exchange, language barriers, rental cars,
and exotic diseases that all third world inhabitants must survive.
But with digital photography comes a host of new problems like transporting
cameras and a laptop computer through through the maze of customs
desks and airport inspections, and then camouflaging that same gear
so that it isn't so obvious that I'm carrying anything valuable, and
then I also have to deal with keeping rain, high humidity and salt
water filled breezes out of the gear.
