What about laying the radials on the ground and then covering with ~ 1 1/2 of top soil? The New England weeds will quickly grow on top and then you can mow right over them. In a few months you wont e

Hi Dick, Well I was talking about how well it might work to cover the radials with top soil as opposed to using an edger attachment, especially where you are laying down radials on ledge. As far as t

I assume that this ATC data is for estimated Windspeeds as opposed to actual measured windspeeds? Do you happen to know how often they update their data and ASCE 7-05 and ASCE 7-93? I also noticed th
