Advancement in technology - isn't life great.
Remember the days when we used 2 coleman lanterns hung out over the boat
on heavy wire inserted in oar locks
Than onto two -3 12 volt batteries with 12 volts bulbs in floodlamps
Still have some of the 12 items in garage - in case might be needed again.
Used chalk line with heavy wgt on one end, marked off in 1 ft ingriments to tell
depth we were in - to set up rods /cane poles accordingly.
