When I was a kid (about 14 - 15 yrs old) my father decided it would be a good idea to replace the 'dirt' in our side yard (couldn't get grass to grow there) with asphalt blocks the city of NY was selling ... I don't remember how many blocks there were, but it was a pretty good size yard, and the 'kicker' was that there were 31 steps to get from the street to the side yard ... we got all the guys in the neighborhood to form a 'chain gang' to pass the blocks from one guy to the next all the way up the stairs ...

PS .. I had to carry my accordion and amplifier up and down those stairs ...
Of course I have the calf muscles to show for it ...
