Use a hose to soften the dirt on the ground first. Then you can use sturdy shovels to dig out the mud. Since you probably have stairs that lead down into your basement, it's best to strap some bags on your dog and train it to haul the dirt out. Alternately, wait for the dirt to dry and place it on a large canvas, which you can fold up and haul out.

Watch out for electrical wires and foundational posts while you dig. It's never fun to get shocked or have your house fall on you just because you wanted some extra room for your model trains! If you encounter cement, be careful breaking it up with a sledgehammer because it may be important.

Finally, you can use the Shawshank Redempton technique to get rid of the dirt. Simply put it in your pockets as necessary, and sprinkle as you make your way around town. Just be careful not to let too much out at your desk at work - your coworkers might get suspicious of mounds of dirt.

Good luck!
