If you'll be punching holes in the bottom who needs a lid?

Mike's idea up there ^ was to cut off the top an inch or two below the
rim, then 'bell out' the inch or two of drum still attached to the lid,
so the lid could sit on top of the drum as weather (rain) protection
when not in use. Brilliant, I thought.
