Capital Township holds a good share of Springfield's old shade — the bur oaks and sycamores that make an August walk bearable west of Washington Park. Double D & Son Tree Experts, LLC prunes with that inheritance in mind, thinning a crown enough to let the wind pass through without taking the cool out of the yard. Trimming keeps limbs off rooflines and away from the alley wires; a tree removal, when a trunk has finally gone hollow, comes down in sections so the flower beds below never know it happened. Thunderheads build over the Sangamon on hot afternoons and arrive in a hurry, and the cleanup afterward is what turns a blocked street back into a street. Steady work, in a place where the trees are part of the address.
