Of course, I had all kinds of help. One of the days I had all three gk's helping. (Note to self: get more shovels. Everyone must have his or her own shovel.) And after a lesson on what was and was not a weed, we did actually get some work accomplished. Although a good deal of time was spent on spotting and counting "wormies".
"Kids, don't hurt Grandma's wormies....they're good for the soil."
I still have a ways to go. The largest one is untouched.
