Ah, the ditch. The lovely, filthy ditch. I spent a good chunk of my childhood adventuring around this area with my brother and our friends, to the horror of my mother. Not only was it highly entertaining, the ditch acted as something of a secret network for kids on foot or bikes to travel between neighborhoods. This particular T-intersection was one of the more interesting parts of the ditch that winds all over Clear Lake, because way back in the 1980s, it was possible to cross it in the concrete areas. It's more overgrown and less inviting now, but it could still theoretically be done. But I wouldn't recommend it. Just walk along the side of the ditch at the top and you'll be in good shape. Be advised a few dogs in backyards might bark at you as you walk by. You're looking for a good-sized cache that is meant to blend in, but perhaps you'll notice it anyway.
