Boy, this forum is slooooww. I just want to say that using my kids old swingset frame has been the best thing ever. I put cement reinforcing mesh (about 20 years ago) on one side of the swingset and have grown winter squash up that every year. I added the mesh over the top too and held it up with shepherd hooks. The squash always grows up over the top. On both ends I put the mesh up for sugar peas/and/or pole beans. then underneath it I put a couple 50 gallon food-grade stock tanks for various other things.

I also took some cattle panel and made it into an arch to grow cucumbers up both sides and it works great. I think vertical gardening is a great thing to incorporate into the rest of the in-ground garden stuff.
