Gentlemen, I have a particular spot in the yard where I always piss when I'm outside which is most of the day. It's convenient and not in view from the neighbors or anything and pretty much serves 90% of my daily pissing needs, and there's not really any other good spots that can serve the same purpose. Naturally it is a rancid smelling piss-mud-pit.

Is there a way that I can construct something relatively minimal which reduces the rancid mud aspect? I'm not trying to make a full on outhouse here, and I am never shitting in this thing, so it just basically needs to facilitate the liquid getting deeper into the ground. My first thought was basically just to dig out a hole and fill it with gravel but I'm not sure how effective this would be.
