Reply to "Coffee grounds"

LOL - In the 60s I would dry used coffee grounds in my mom's oven and then use them for dirt roads and truck loads. The only issues - make sure to keep the area dry and low moisture levels.  The humidifier broken down while I was away for a month and MOLD started growing in some of the coffee grounds that did not get a clear spray overcoat.  A Vermont Bridge Engineer.
