Speaking from experience, if you are going to hike DO NOT TAKE A SHOULDER BAG. Ow. A five mile hike and a shoulder bag was all I needed as incentive to purchase a backpack. I have not regretted the purchase at all.

I have never gone to a workshop but I would take the opportunity to learn the wista. Plus a monorail is a B**ch to hike with and set up. It is pretty discouraging when you are missing the light because of how long it takes to set up the camera.

Take ZIPlock bags to put your film holders in, including the quickload/readyload/polaroid holder. It is a known fact that if there is a speck of dust or drop of water within a hundred yards it will be drawn to your film holder. Not the guy next to you, yours.
