Like the title says, I would like to build a 85' long redwood fence that looks the same on both sides. Similar to this:
I will use redwood 4x4 posts and 1x4 or 1x5 pickets, but how is the structure of the fence built? It looks like the stringers are 1x5s on the top and bottom AND on both sides with the pickets sandwiched down the middle?
Any fence building advice would be appreciated! I'm located near Sacramento, CA if that makes any difference.
