@pooriggy already has you covered but I'll add that this place is really well drained. I haven't been there in about a week as I am fighting a nasty cold right now but I've ridden here the day after inches of rain and my bike didn't even get dirty. It is true that you can't mess up what isn't cared for but I don't particularly enjoy riding through endless sloppy mud, whether anyone cares or not. You won't find any mud at Hartshorne. I'm pretty sure you could even ride this place in the rain and not get muddy.
