I’m going to try that this year. It sounds like a terrific method.
I imagined this during some cloudy daze of the 60's or 70's (did I say cloudy daze?) and it was first, a ladder.
Over the years and decloudification, I added (in my mind) wire fence to the top of the ladder that was resting on 5 gal buckets at each end.
Last year was the first time I did it as described.
Thanx for the comment.
