Thanks everyone for your advice and your shoulders...I do feel better.
I like the net idea Arlene...in fact I was thinking of using netting against the back of yard and let sweet peas or something climb it..
I think I'm going to check into how much it would cost to have the raised beds with the fence done just on her side. The more I look at it the more I'm really being to love it. Like I said...may have to build it this year and fill it next year!!
If she would ask why I'm doing the fence I'll just explain to her the way I want my garden and I know she doesn't want stuff on her fence and I don't want to do any damage to her fence since I want to hang feeders, plants etc.
