Got my new pallet forks last week. Which is good timing because Lowe's just brought ten pallets of paver bricks. I'm planning to create a patio in the back yard and would appreciate your thoughts on doing it. I think my biggest concern is getting the grade right - I want the water to drain correctly and not puddle or run back toward my house. I expect the patio to be about 30 X 40 or so. Any advice?
