It is huge (74x64 and 1 foot deep) and I just found out that it will cost us a minimum of $5000 to fill, with gravel or woodchips, not even sand! Whew! Not surprisingly, in these economic times we are not in a position to drop that kind of money on sandbox filler.
So, I am looking for clever ideas from all of you creative people out there, on what to fill it with that will still entertain my kids, but cost a whole heck of a lot less money!
