I got a few questions about the box I posted about yesterday, so I thought I'd answer them all here at once. First of all, to correct what I said, the brush holder does not come with the box - it is extra ($25). I will say that I've been using a PVC holder for years and a super side benefit is that it keeps brushes wet. I admit I sometimes go many days w/out washing my brushes - just putting them in the holder every night. hee hee
The fold out box part is separate from the panel "holder," but the holder is literally just a fancy stick that clips into the tripod. So it is super easy to stick in a pocket of your pack and/or strap it on. The model of the Kelty backpack I got is "Redwing". It is plenty big enough and has a pocket that will hold my laptop for travelling to workshops. It cost about $100.
By the way, these leaves (above) are from my front yard. It's been beautiful here with the falling leaves.
