Used to ride motorbikes a few years ago, put my visor down one day as I was going to speed up to see a wasp on the inside about half inch from my nose! It was enclosed with not much space to fly around in, stopped quickly to sort that one out.
Yesterday going down a hill on the mtb on a busy narrow road I heard a thud on top of my helmet and felt something in there, couldn’t stop for a few hundred yards cos there’s no where to stop without stopping the traffic too and I’m sure I could still feel something there, I worried for those few hundred yards that something was going to sting me! Nothing there by the time I stopped and got me helmet off?
