I used to have a dumpster and have it picked up every week... but it was too expensive. Plus where I live we pay for 4 dump days a month in our taxes. Only bad thing... can't take manure there. We made buddies with the attendant and he's let us before, but we don't want him to get in trouble.
So we just took it to the BIG dump today! Filled up the whole back of our pick-up truck. It only cost $18.47 and it was a whole month's worth of 3 horses!
