Anyone have one of those magnets on wheels used to pickup nails etc?
Might work out well picking up some of the little stuff anyway.
The rest of the smaller pieces looks like it will need to be sifted through screens to have an effect. Then we're talking brooms and dust.
Best just go for a uniform smear.
I'm planning on making it down there for this event. Looks like about a 3-4 hour drive. Capabara or gtturborex can you post GPS coordinates or a Google earth pic/URL?
