Everyone who plays Basketball wishes they had a back yard court, I know because when I was growing up I wanted to play all the time. I always wished there was a Basketball court in our back yard and I still do, however I just don't have enough room. Below is a list of prices for you to create your own backyard Basketball court. My math comes from the court being NBA size as well as the cement being 3 inches thick. (I have been corrected by my dad who works in the construction field that I would be best to use 6 inches of cement due to the Basketball pounding on the cement) so double the cement cost. 

If you live with your parents and they think that building a Basketball court would be too expensive show them this post as this may change their minds.
