well, maybe not more than anything - saturation bombing, a herd of stampeding elephants, paving the whole place are things that readily come to mind. However, yes it is likely to be a slopfest, and yest biking in those conditions will damage the trail.
Yeah you really shouldn't go riding anytime this weekend with the warm teperatures that were suppose to have. It's going to be a mudfest there. Keep in mind that you will leave many ruts in the trail and when people ride when the trails are good they are going to be hitting ruts the whole time. So don't ride now and have an awesome ride later on in the spring.
