University Park sits green in the middle of Main South, and the streets running off it are dense with houses and short on spare ground. Jean Jacques Landscaping keeps those small yards in order with mowing, trimming, edging and cleanups in spring and fall, then plows and shovels them clear when the year turns hard. Working tight lots asks a different skill than working open ones, since every pass has to be planned before the first one is made. The good end of it is a walk cleared to the step and a driveway with room enough to open a car door. And in September, in a yard the size of a rug, a line of grass cut dead straight.
