I got quite a surprise today when I showed up to mow one of my regular accounts, the last one of a long day. White flags everywhere! I've dealt with white training flags for buried invisible dog fences before and usually they're in a straight line, so although it's a bit of a pain, they can be dealt with. Well apparently they got the wireless invisible fence because the flags are in a circle across the whole lawn about 50 feet from the house. I didn't count them but there has to be at least 50 of them about 6 feet apart. This is a good sized lawn, probably about an acre of turf, nicely striped. I got a pretty good chuckle out of it but couldn't for the life of me figure out how to mow this lawn with the flags in place other than mowing "tractor-style" in a circle and I'd really hate to do that. I rang the door bell but nobody was home. I left and found another lawn to mow!
