Does anyone have any experience with garden wall replacement?

6. We get them for about 5 bucks apiece

delivered, even

Problem is...they do tend to rot out inside, and the snakes love em. we have copperheads and rattlers around the house in the woods,
as well as not venomous big snakes, like rat/King ones, that stop you dead in your tracks as you try to see the head or tail just to make sure.

Luckily, at this stage in our retirement, we don't use the railroad tie steep steps, and don't have to mess around with the driveway RR ties, our handy man does.
But a replacement option is always nice to have handy, they do rot eventually, esp. in the rainy season.
