So how many supervisors does one worker need?

I post this not because it is great but rather because it is an example of what happens when you skip the right chance at a shot to begin with.
Coming home from a lunch meeting today I passed this water utility crew working. One the first pass all 4 of these guys and one more who is
now out of frame where lined up, right next to the one at the top of the ladder in this shot, on the side of the hole staring down at the one
guy in the bottom, working . I though "That would make a cool PAD. Some real "street" photography there" and I then I drove one with my
camera left in the bag. Then I reconsidered and decided to go after it like I should have done to start with. Too late. This was all I
could get after having to circle the block to get back into position for the photo. Lesson to me...take when it presents itself and
or miss it completely.
