Technically yesterday, now, but... between my roommate and I, we cleared back probably... a good hundred feet of brush, vines and undergrowth. Now to kill the whole area with 'fuck-you'-level herbicide, KEEP it dead, then come next year, we'll rake it all out, cut down a few trees, and rent a wood chipper for a weekend... then we'll dig out after that, and plant grass, and officially expand the lawns.
