Dang....! Honestly, I hope it's worthy of such a trip. Are you confident in the ability of 13 year-old high-speed Kodachrome? I trust you are... (but I would test it, just to be sure)
But what an amazing journey; 57 years... I hope color film is around for another half-century.
Thanks for the trade Karl, I'm confident that it's going to the right person.
