Sharonquilts...we did something similar with our kids...Crater of Diamonds in AR...my son dug a whole nearly as deep as his height...my daughter had seen Snow White too many times and seemed to think that large cut diamonds and other gems would just be lying on the ground; plus the day before we went to a small campground where you could find big, beautiful quartz crystals easily...my husband dug faithfully and I napped between the furrows...we'd been camping and traveling for days...that vacation and the "diamonds" are still a fond memory for all 4 of us.
