The soil will turn to slick gumbo mud when it gets too wet. It will turn to dust if it doesn't rain enough. Thousands of people walking, riding and driving on grass and alfalfa will make dust by the end of the week. Expect it and accept it. There's no amount of watering which can avoid it.
Roads are either gravel or dirt trails.
There is no pavement or concrete. You're in the country and in a pasture. We've learned it's different strokes for different folks. So we let you choose your own on a first come-first served basis. We encourage a quick drive-through inspection before setting up.
