I've been paying $11.50/ton for #53 crushed limestone and the same for the larger #2's the last few months.

Put in a long driveway with the #2's as base and have been adding #53's a couple tri-axles at a time as needed.

Using Shelby Materials in Shelbyville, and they have been great!

I haven't inquired about pea gravel prices there yet, but I had planned on using it for spawning base when I build my pond as well.
