It's a start and I survived....

4 80-lb bags of 3/4 minus gravel
3 50-lb bags of sand
56 landscape blocks (at ~30 lb each)
4 2-cubic foot bags of garden soil (~75-100 lbs)
A full day of labor

That equals about 2500 lbs of landscaping materials, some sore muscles, and an almost finished raised strawberry bed (I need to cut the last stone, twice, and I don't have the right masonry chisel.  I also need another bag of soil).
