Mirror folds up in high winds: solved (but not pretty)

Hmmm . . . I forgot about ferries. Someday, when this silly bug goes away, we are heading back to British Columbia, and I will need to pivot the mirrors.

Yeti, great point about the black cable ties.

And Old Biscuit, the ugly lumpy plywood block is doubly offensive to me -- I am a reasonably skilled woodworker, and I usually work in oak or walnut. Construction grade plywood scrap is an abomination, but this is just a prototype, I keep telling myself. ;)
