Okay I'm going to give it a shot this weekend - just one more thing I wanted to add, I saw in itsreallyconc's post a mention of this only being 5 or 6 sq. ft. I think the pictures might be deceiving. The entire "hole" I'll call it, is only 1-3inches high in most spots and maybe 2-2.5 feet across, its really pretty small. Does that change the approaches you've outlined or same approach smaller quantities?
