1. Literally, a front-row seat next to a boxing ring (thought to be the best place to watch the match). Wow, you got a ringside view to that fight? That must have cost thousands!
2. By extension, a place in close proximity to a certain situation or event. I unexpectedly had a ringside view when a fight broke out at the bar. Living near this forest my whole life, I've had a ringside view to witness the change in the population of birds.
