Thanks guys, - very funny.
It's not as bad as all that. My friend and fellow Torontonian Nick Devlin shoots with a 5D MKII and he has "volunteered" to carry my loaner body and some of my lenses. I'll simply pop into his cabin when I need anything Canonish.
The D3x and a couple of lenses will fit in my Kiboko carry-on backpack. It just means displacing a few Sony lenses that are equivalents.
The P65+ body and lenses system is being brought by Kevin Raber from Phase One, so in fact I'll be free as a bird. Just one backpack for travel. When in Antarctica I'll simply pack my bag each day with an interesting combination of gear. What a bother, but hey – someone's gotta do it.
That problem solved, now to find time to sleep.
