Even before he started to sell concrete, Michael wanted to stock up on a lot of it first. After all, this village would also end up using a lot of concrete to finish all the houses and buildings under construction.
So, he instructed some of the Mankeys to journey out into the desert to try and find a good lime quarry they could tap into.
Fortunately, once they returned from their scouting, they found a big one very near to their current location.
He instructed them to start mining all of the lime they could get. And to make their jobs easier, he lent them the automobile to haul all the limestone they mined for the day.
Of course, he had to teach them how to ride it first. Thankfully, one of them had a talent that allowed him to learn driving quite easily.
