I'm putting heavy duty chain link on the run but I don't have the energy left to dig out a 6ft. apron (size of the chain link). . . I can't find anything heavier that 19 guage 1/2 x 1/2 or 16 guage 2 x 2 wire here and it's a fortune to have it shipped. I was thinking of putting the 2 x 2 wire in the ground attached to the bottom of the run then stake some of the small wire on top. It will be a lot of work and expense and I'm wondering how long before it rots out in the ground? Has anyone had to replace their apron wire yet?
