Stop in for a cup of coffee

Do you have to wear a Snell 2015 approved helmet on the riding mower under the walnut tree? Or will one of those DOT approved pudding bowls with chin straps suffice? :lol:
I haven't, but really should get something. I need to look if my son still has a bike helmet around that fits. The biggest tree down back is probably 70ft high. No joke if one would hit me in the head. I have had a few near misses over the years.:eek:
