I cleared out as much dirt as possible and wedged the shovel under the edge to pull up with all my might. Embarrassingly enough, I fell when the shovel slipped off while I was pulling up, I darn near broke my dappled willow and hit the grass flat on my back so hard my glasses flew off. I'm pretty sure I heard the giggle of a fat ass squirrel, too...
Finally, without any more 'America's Funniest Videos' moments, I had it loosened enough to wiggle and pull it out with my hands. And, poor flagstone was freed from it's earthy prison.
Thanks, Boozie Susie for burying 100's of flagstones in our yard and planting grass over them!
Who knows how many more we will find....but all of the stones in our mini retaining wall were once underground, so I'm quite sure there are still more in there. Oh happy day.
