I'm happy about the interconnectedness of my current project

I'm not sure if it's stacking functions or getting multiple yields or something else but my current fencing project is pulling a lot of things together.  

On the surface I'm building a fence with pallets and cedar posts.

The fence is a zig zag design and 5.5' tall.  It will be mostly opaque.  It will provide many functions:

Block view of neighbor's back yard

Keep deer out of my food forest

Block winter wind

Create angled sun traps for pushing my zone

Cover up the bottom dead branches of my neighbor's pine trees

Opportunity to showcase stacking functions and intentional design to visitors

Learning experience for me about using cedar posts and laying out zig zags

Getting the raw materials involved:

Purchasing $15 of exterior screws

Collecting free/waste pallets from a local business (6' by 32")

Trading my labor for cedar poles (7 hours for 32 posts)

Helping a fellow homesteader - his cedar poles and saw logs got cut and peeled much quicker than he could've done it himself

Installing the fence yielded:

Post hole digger sized chunks of sod to patch in a low spot in a trail through the woods.

1 gallon of topsoil per post for a lasagna garden

Some small rocks for future projects
