Rain and more rain, I live on top of the ridge between the Yellow River and Blackwater River with about 6' of elevation from the northwest corner to the southeast corner of my place but most of the fall is in the last 150' with only 1.5' in the first 400' and my yard is overflowing even with the drainage swale's I've put in. Going to need 2 or 3 dump trucks of lime-rock or gravel to fix my driveway if it ever drys out. Come June I'll want some rain but I've had more than enough the last couple of months.
