Seedling Benches, Starting Over

I suppose that 17 years is plenty long enough for seedling benches made out of wood, wire fencing and screen to last.  For the past 3 or 4 years in fact, we have been propping up rotting 2" X 4"s on one of the seedling benches that has been threatening to collapse.  So this year we decided to rebuild all of them and replenish them with brand new potting soil.  Each raised bed is 20 feet long by 5 feet wide and all of the boards are put together with screws so as to increase sturdiness.

Two down, two to go!
