As a matter of fact I did have my rain barrels in place.Collected slightly more than 2 gallons each.Would have done better if they were connected to gutter downspouts.In the process of demolition of yard swing made of 4x4s.I will construct with already sourced materials to build a 2(X) barrel rack attached to gutter downspouts.I try to recycle/reuse all materials I can.I have two unmolested food grade plastic barrels waiting in the wings.Greener
