Sorry in advance, because I guess this is an unanswerable question. I
need some topsoil, and have managed to get a good deal, but I have to
buy a minimum of 20 tons. Trouble is, I really can't visualise what 20
tons looks like!

The space is pretty big - about 90 feet by 50 feet, though I want to
fill only half of that if possible - perhaps to a depth of up to about
3 or 4 inches.

I know this is a vague question, but do people think this is way over
the top for my needs? I don't want to end up with a massive hill in my
garden!

Thanks

Will
