reason I have started this topic is due to my ride this evening. Theres one spot that we ride and there seems to be a couple or a old lonly person but they find it either amusing or just a way to move us on by throwing pins out their window and scattering about, some times they also do it when we are there landing on us. I managed tonight to get four in just my front wheel making it flat in secounds not relising untill I had got home that there was another one in my back wheel So tell me you most anoying problems when riding, would just like to have a general discusion on this.
