Your cart and story remind me of a heavy-duty plastic cart that I purchased for Ben to bring the 50-lb bags of corn for the ducks into the house. My old guy was actually carrying them - we buy two at a time - from the car and through our house to the backporch storage room. Of course, one-by-one, but still remarkable for someone in his 8th decade! The cart has probably added 5 years to his life! And, I get to use it for my gardening ;)
