We have a 10ft piece of plastic drain pipe/tile laying on one of the trails to be buried under/across the trail to help keep the water level down during our winter rains. Well the boys came across the pipe the other day and were not sure about it.
He gives it a sniff,
but keeps a close eye on it,...
Tanji bravely approaches the pipe.
Uschi moves in to investigate again,
and gives it another sniff.
I had to mess with him a bit,...
and made a humming noise into one end of the pipe.
