very interesting discussions. I only set up on the lawn several times a year probably... sometimes when I just have a few cuts todo etc. I just do it. my van was also on the lawn since this was at the rear side of the house and the owner said no problem.
so when done with the 2 day job just through all the debris in the van, and now it is piled on the side of my house waiting for a bigger pile then to dump!
but hey it works !
