One good rain and a child could push it over.
HELLO

There's some science to setting a post properly.
And in building picket fences. Cross pieces with bevelled cuts on top.
Same with the slats. Bevel on top. Transluscent exterior stain.
If its done right the fence could last 50 years or more.
Only set in about a foot? No concrete? Not much of a job.
It was coming out anyway.
