Another Safety Tip. Use Sunblock, wear a large brim hat. I have spent a lot of time in the sun over my 55 years. Got burned many times in Vietnam, on the jersey beach. About 5 years ago had a brown spot develop on the side of my face near my ear. Doctor said it was nothing. This year, after my family's insistence, I made the doctor due a biopsy. Sure enough, Malignant Melanoma, the most deadly form of skin cancer. Was operated on 2 weeks ago, took out a large part of the side of my face. Good news is that he was a plastic surgeon and am no uglier than I was before. And he got it all. Doctor said one more year and it would of been too late. I urge you all to use sun block and wear that hat. Skin cancer is easy to get and could kill you. Be safe and happy mowing.
