legal wheeling question
My friend is a farmer and own over a thousand acres of farmland. years ago his father dug drainage ditches to drain his fields of excess water. these ditches and drainage fields are bad ass to run the rigs through. these ditches are man made, and water flows through them. in some areas there are cattails, but we dont mess them up. since these are manmade, and are on private land we really tear up the mud, but rebuild them later in the year. Are we breaking the law??
