I've gone down this route before...and believe it or not, I talked her out of buying a cargo trailer.

After going to pick up a few loads of mulch with the Ford Focus I did the math for her.

cheap mulch was $20 a yard I think, but came with a 120 km round trip, x2

Even in a Ford Focus it's still going to cost you in gas. At the time she didn't drive so I had to come along and after all was said and done you could have someone deliver it to your door for that money.

Next year she was at the local diner when a tree pruning crew was having lunch. So after being out of town a couple days for work I came come to find about 6-7 yards of mulch dumped at the end of the driveway. So I had to find elsewhere to park

This time around she stumbled across this pile for free down the street from the house so I can....let's say accept the line or thinking. Not so much filling the car with mulch but left unsupervised these things will continue to happen.

I have mixed feelings about her getting a driver's license
