barrel filled with water with a row of aerator tubes fastened around each head pulled by hand? Less than 1000 sq ft and too hard for foot-stomper aerator.
Magically someone was passing out flyers to do aeration in the neighborhood this week. This is the just the 2nd time I've seen someone come by in 20 years. Prices listed vary from $80-160 front and back, depending on any extra services.
