Our water barrels have been out in the yard for long enough. They used to be at the back of the shop - where the new boat cover is now.
So, we washed them up, and have stowed them inside the shop. We'll put plywood across the top to use them as shelving or a work table.
We have 4 barrels that are 55 gallons, and 5 that are about 13 gallon size. The smaller blue ones are easier to handle when full, and a good size for whatever.
Later in the week we'll add bleach and fill them up with water.
