Gear/items I brought in addition to the Strada Micro and paints:
Manfrotto tripod. LOVE IT... but it took a beating on this trip. It's heavy (aka sturdy!) and not particularly small. I pack it in my old Kelty backpack but even still, our art gear got packed into really large dry bags with other people's art gear and my tripod just seemed to be in the way. Not sure how I missed this information too, but there is sand in the Grand Canyon. SAND EVERYWHERE. You eat it. You have it in your hair. It is in your sleeping bag at night. It is in your paintings. It is now in my tripod. Many of the joints and levers became increasingly difficult to open and adjust because of sand. I brought a little sketchbook and some clips, palette knife and pliers. I brought my Holbein turp container and a bottle of Gamsol. Both leaked. The boats are constantly moving and bucking in rapids; people are tossing bags and sitting on bags... they leaked. Not badly but still annoyingly. (Speaking of leaks! first night at a camp... opened my toiletry bag and EVERYTHING IN IT WAS COVERED IN SOAP. Thanks Dr. Bronner's. I had to wash batteries in the river!)
I brought 6x8 and 8x10 Raymar wet panel boxes. I also had a 9x12 panelpak with 2 panels which I never used. Panels.... I brought Trekell canvas panels on foam (loved them, super lightweight), Gessobord panels and Jack Richeson pre-toned panels in beige. I pre-toned my other panels with red or sienna acrylic before I left.
Of course also: viva paper towels! I use Gear Tie clippable twist tie 12" to attach towels to my pochades. LOVE THESE ITEMS! 2 values of grey felt markers, pencils, 3 carbothello pencils for sketching on my panels. Latex-type gloves for my hands... I always get turp/paint on my hands! and painting hats. HATS. I brought a crushable straw hat, slightly cowboy or bonnet depending on how you fold it on your head, an SPF type beige hat (never wore) and my trusty baseball cap.
