Cool. I love how simple she makes it.
I will add a couple points: If you are going to use plastic pipe, use conduit (the grey stuff) as it has UV inhibitors so lasts longer.
I prefer to use metal conduit and a small $40 hoop bender.

Each piece costs a bit more (but about the same as a piece of PVC and a rebar stake) but they handle snow better, last longer, and no plastic. I think they are a better value in the end if you are doing enough to justify the bender.
