Once the sub-base was close to where I wanted it, we outlined the arena (120 Meters X 20 Meters) with a string line. The previous owner had lined the driveway with railroad ties -- we didn't like them there, but they came in handy to define the arena boundaries. The 4-in-1 Bucket was a real handy tool (as you can see, I sit too close to the dinner table to lift railroad ties by hand /forums/images/graemlins/blush.gif)
