I put an ad on craigslist offering free coal ashes. I now deliver to a gentleman that has a long country driveway every few weeks.
Usually two 45 gallon totes. It's a nice country drive and he appreciates it very much. Gave me a bunch of deer meat last trip.
If needed I use some for the bottom slope of my own driveway.
The guy across the street has this long sloping driveway that is paved and has been taking them for the last two months once he found out we had them, I only have to roll them over to the door in the garage.
H e comes over once a week and takes the tubs in his truck and then brings them back empty.
He must have enough now, not sure what he's doing with them now.
Other than that my Brother has a spot he's trying to fill in, ashes will never do it alone even in 30 years but it's some help. I think I might put a sign out front once the guy across the road has what he wants becsue having them removed by someone else can't be beat.
