Last Friday I had my old 90' gravel driveway dug, and prepped by a local paving company. They took out one bolder that was almost the size of my taco's 6' bed, not to mention 4 other slightly smaller ones. They barely got them into their dump truck. Took several huge dump truck loads of reclaimed asphalt to fill, and compact the driveway to get it ready. Now gotta wait a couple weeks for all to settle before they can put 4'' of new asphalt on top, and we'll be done. When they did my parking lot at my shop years ago I think it was less $$$.
