Yup, I have about 1000 ft of driveway I need to re-top. The cost of doing it in gravel is an order of magnitudes cheaper than any other method other than just regrading with a tractor, which would need to be done again in a year or two. The current gravel was put in 30 years ago and it's just now getting to the point that it's bad enough that I need to do it.
