I ususallly do walk throughs before I mow and also during a quote or the first time I mow and its kind of scary walking around a corner having no idea what awaits you. There could be a loose dog, snake, rabid animal, who knows. I now grab my a 4" switch blade before I do a walkthru just incase. If push comes to shove it's nice knowing I have a fighting chance. Sure a gun would be nice but that is a big responsibility... and our Sherrif hates guns so he'd never give me a permit for the reason of "self protection" What do you carry? I've been also considering dog mace.
