This one was a close call. I actually had to come back and finish this one. This probably took me all together in time spent an hour or so. I think I used 3 black and 2 white cans on this one. I was just finishing the fill in when I heard a vehicle pass over above. Talk about a rush of adrenaline, my heart was pounding so fast but the excitement was great. So I ran, and as I just left the area, the vehicle pulled in on bottom. Ended up being lucky and getting out in time. Next day though, just came back and finished it. I probably wont forget this piece because of the experience I had.
