Across the way, the Gaggeldub family is setting up their sound and we’re all watching with interest because it’s the first time we’ve seen this solar powered soundsystem. They set some poles and string a canopy from the side of their truck. Off to one side, they set up a camp kitchen. Under the canopy they lay out a carpet and then they arrange their soundsystem. The four bass scoops and two mid and top speakers are painted a cheerful shade of green and they look brand new.
