I certainly sympathize with the blood thinners. I was on blood thinners for 3 years following heart stints. As it happens, I dropped my bike today (riding too fast on a stretch of wet slippery curved road). The helmet was not involved. I got a minor case of road rash. When I was on blood thinners, it would have been blood everywhere, a hematoma, and no riding for 90 days while I recovered. Thank goodness the doctor took me off. Drive carefully out there, and best of luck.
