These are all cool ideas but around here a stick of 2x4 wood is cheaper than a stick of schedule 40 pvc pipe. I reckon the pvc lasts longer though, that's more the point right? Just trying to realize the advantage..

Even with all the snow we had this winter, only one time did I have to run out and actually knock it off so that it didnt break the pen.

Our run works very well for our very uneven lawn because of its flexibility. Good luck! Oh--its 8x10 for our 8 girls.
