Just took the dog for a walk and ran into them again, so they went all the way to the end of the street and back (at least a couple dozen houses).

I mentioned that they are doing lot of walking and asked where the heck their truck was and they waived and said "a long way, somewhere over there".

For what it's worth, they were good looking, well kept and friendly. One white, one black.

I voted light scam, that's what it feels like to me. I'm guessing they'd do a crappy job of hanging shitty gutters and gouge us.
