Tim - the troughs in the pictures aren't mine, they are already onsite. Those are several feet deep, mine are only 1 foot deep
Mine won't be moved until later in the spring. I think I'm going to have to be somewhat aggressive - just heard back from the person in charge and she said she thought it was only 1 trough, 6 won't work
(according to her, but I know it will, I just have to explain what I have in mind
)
