What can I replace a railroad tie for a bumper on the driveway?
My driveway is on a bit of a slope, and runs right to the grass lawn. I have 2 creosote railroad ties as a bumper to keep cars from running on the grass. It's decaying and time for a new 'bumper'. I need to come up something other than the ties, that will hold up to weather, watering and bumps from car tires, and still look nice. Ideas?
