This arbor is so attractive.  East to put together.  We dug four holes to set the legs in the ground, poured in some cement, let it set and it was done.  I have Sweet Autumn Clematis growing that comes up every year.  So the vines were growing, sprawled on the ground "waiting" for a home.  Once the trellis was in place, I just "fed" the vines in the lattice and now they are happy and growing up the arbor.  Love it!
