Planting a fence?

Bruce spent most of yesterday and today laying the wire for an invisible fence (all the way around the property!). David has been "helping" him most of the time. Today, apparently reflecting on the vegetable garden which he helped to plant the seeds for, he asked his daddy, "Will it grow up in a lot of years?" He has been hoping for a "big" fence and thought this was the way to do it! How cute is that?! PS -- It was 80 degrees at one point today...I was shedding layers faster than I could get the lights strung and I ended up with bare feet, sleeves pushed up, jeans cuffed into capris...it felt funny to be hanging Christmas lights in 'summer'...!
