On a Saturday the old courthouse square fills up and the whole town seems to be within four blocks of itself. JMC Lawn Care of McKinney put the town's name inside its own, which is one way of saying the route never leaves home. Mowing, edging, trimming and cleanup on the streets that fan out from the square and the ones that run past the loop, straight through the growing season. Bermuda in July wants cutting every seven days and says so loudly when it does not get it. The part worth showing up for is pulling away from a yard and watching it hold its shape from the far end of the block.
