oooh you really have some set up there. I used to do film photography in high school, (developing film included) and I still love the look of film, with is grain and everything. Of course nothing beats the instant gratification of digital, but part of me still loves the old-school film look. I do really love circular polarizer filters. It really creates such nice crisp pictures of blue skies and water.
I am not sure you have this on your list already, but one thing you might want as part of your "kit" are ziploc bags. I just wrote this as part of my next installment of my TR but thought I'd share it with you here in case you dont' have time to read it before your trip:
"A good tip: I brought along a few large gallon-sized Ziploc bags that I was able to store our used ponchos in. That way, if it stopped raining, we can fold up our ponchos compactly, put them in the bag, flatten it to get rid of all the air, and then seal it and store it in my pocketbook or another bag without creating extra bulk. It also keeps everything else in your bag dry, especially things like cameras and cell phones. Ziplocs are great! They are like instant space bags (the kind on tv where you vacuum all the air out)"
Your trip is approaching fast! Can't wait to read the rest of your TR.
