Blower-vac! I know what you mean about the mini-tornado. My neighbor showed me how to use it (obviously I lost something in the explanation). All that happened was there was a huge tornado all around me with dirt, leaves and debris. I could not direct it anywhere but right around me, kinda like Lynus on the Charlie Brown cartoons, you know. And apparently, I was either grinning or grimacing through the whole ordeal because when I went in the house to clean up, there was dirt stuck all over my teeth! Gross!! I gave the darn thing away to the neighbors son so he could start his own lawn mowing business. I just sweep everything after I mow now! Those things are some kind of torture machine. But, it was kinda funny to chase the dog with it!
