Susan, the GH has been a great help to me for starting my seedlings (actually I start them inside under lights, then move them out to the GH around mid-April); I also put up a couple of "hoop houses" that I bought on E-bay, where I can start growing things in the ground much earlier and keep them going longer. I'm sure you can relate when I say gardening in the north can be a challenge!
It was actually the hoop houses that I used the ground anchors for -- photos of that project last year can be seen here:
