Just checking in occasionally from Colorado, USA. I'm a US Soccer Grade 7 Referee and work youth and adult amateur matches. It's interesting to see our questions, debates and complaints generally tend to be similar, regardless of the name of the game. My vision became terrible when my daughter was 7 and her club need volunteer linesmen for matches, and then it became much worse when I took the referee course and apparently passed it. That was 20 years ago and I still can't see anything clearly when I cross the touchline.
