I have both a comment and a question. Comment: As we all think about not wanting to get hurt from falling, let's also not stop having our bodies work. My mother, in her late 80's, moved to a house that was one storey, but with an unfinished attic. Pretty soon, she had the attic finished, so she would have an upstairs, and she moved her bedroom and office up there. the stairs wre very steep and shallow, but she happily managed them, including after breaking first one hip, then the other, then the first one again (never because of the stairs,) then, finally, after shattering her kneecap,(again, not from the stairs,) my siblings talked her into moving her office and bedroom back downstairs. That was the beginning of her decline. If you get rid of stairs, then have some steep hill you enjoy walking up every day.
Now for my question: I have fashioned a few raised beds out of broken black Rubbermaid cattle troughs/stock tanks that I found at the dump. They had cracked bottoms, so they couldn't hold water....perfect for raised beds. I put small logs and various plant debris in the bottom and topped it off with lots of leaves and compost. Everything I have put in them has grown quite happily, even the cold weather crops . What I really like about them is their height, close to 30" too high for the groundhogs and nice and easy on our backs. The question is, how to get more of them or something else that is that high and that I won't have to spend a lot of money on. When I price getting enough rough cut 2-by lumber, the raised beds get expensive fast, and I don't want to buy intact cattle troughs (way too expensive) simply to drill holes in the bottom. Any suggestions?
