[TheForge] OT: Spring tile question

[Bob Ehrenberger]

Andy,

Around here you can get either gravel with fines, of clean gravel.  Both 
would be crushed limestone.

For fill on septic system drain fields they get river gravel which are round 
smooth rocks.

Thanks.  BTW, what exactly is "washed gravel", AKA, "washed stone"?  Is
it a generic term or is it jargon?
