This is rather OT, but I sometimes get to shoot concerts because I know the MC and he wants the photos for his portfolio so he can get me to shoot, then I can watch and take photos of a ticketed concert as wellI had to go through a lot of steps to even shoot an S-league match. For another larger event, it was much easier as i had a recommendation. so it all depends how many people you know and just how well you can negotiate to get the job.
And er ok if you guys want to practice shooting sports, I'll say it again: just do it during the A/B/C div matches, it's free, it's open to everyone, there aren't many people and photographers who block your view. Too bad this year's season is already over, but there's always one next year
