DIY cargo trailer

Back in the day I worked at Coke. Every Friday I would
put 3 cases of 20 oz soda bottles in my trailer and trek it home up some
of the longest and steepest hills in New london/Waterford CT. Rain
wasn't bad but wind or snow were killers. And one day at the Super
Market I over loaded it and the axle snapped from the body. That was
during a hot summer day in August. I ended up trashing the trailer and
pushing a shopping cart home with my bike on top. I'm thinking of
getting another trailer like real soon.
