I used to work with a guy that had what looked a bit like a Schrader valve (I never got close and looked) a little bit behind one of his ears. I worked with him for a while but never asked what it was for. Any chance you could give some idea as to what it was for? I assumed he may have had a TBI at some point (I feel like I remember an IED story from him) and it was to relieve pressure or something.
Same, when you were too small to reliably hold on, you ride in the front. I remember the first time riding on the back (probably 4-5) and remembering how much more it sucked because I couldn’t see shit… That was a lifetime ago though lol.
