Thanks so much for all the feedback...when I get myself into these situations I tend to dig into an area and fully enjoy working it with one lens...in this case the flows have been so powerful that I was offered a nice set of challenges, which of course keeps you thinking as you work and later as you review, hopefully to make a few good notes for future reference..
As to the waders Mike..I was indeed alert constantly...we lost a friend off the cliffs at the shore last summer that way...and as I tend to try to get down/into water as much as possible I was finding my butt be swamped again and again in warning and have two tears at 3/4 height that are supposed to warn me of incoming/depth in water.
As to covering the lens with plexi...nice idea in theory or many situations but my tripod (my big gun/heavy) was zinging/screaming/vibrating in the flow and I was just nervous enough about it taking off that I worked with parachute cord attached so that I would have at least a chance to retrieve. The bed rocks kept deserting my footing and there were so many more placements I wanted to get into but just too dangerous in those flows...I'll go back into the group and pull another so that you can see anothewr take on the locale..
PS my pockets were loaded with micro fiber, tissue etc, but it became quite sodden, and hike back out to refresh out of the question as it took too long to get into positions in first place...shot till almost dark each day and glad for it...
You are an amazingly generous community and I hope you know how much I value the time you take to share your thoughts
