Well, since I bought my own house about 8 months ago, and I'm single for right now so no one can tell me what to do ( ), my friends nominated me (ok, twist my arm) to have the backyard track. I plan to landscape it one day but for now since there's nothing back there, a track is OK.
My neighbors just built a pool so I had the pool builder dump all the dirt in my yard. (FREEEEEBIIIEEEE!!!!) It may be too much but I'll give away what I don't use. The dirt is super clean with no rocks.
I'm renting a Bobcat this weekend so I'll update with pics as we build.
