Sounds like a swim meet. Sit outside in 100+ degree weather for 8 hours waiting for your kid to swim 3 events that might last 40 seconds each with the obligatory relay at the end they have to stay for. And some of these go on for 2-3 days. Utterly brutal.Youth volley ball isn't too bad. Pretty exciting, actually. There's always 1 giant kid that can jump serve and spike. Terrifies the other team.
Worst of all - multi-school youth track meets. There's 64 kids on the team. Your kid runs one event in 4 hours - the 1600, which is usually the last event, and it's your turn to bring enough bananas and water bottles for the entire team this week, too.
Volleyball is pretty good too once they get to 8th grade or so and can actually do it.
Soccer isn't bad because they're always moving and it's short. Makes me think how every World Cup the 3rd worlders trot out the "soccer is the most popular sport" and "people from the US just don't understand the game" mantra and soccer becomes relevant for a couple weeks. When you're in a country with no NFL, NBA or MLB I can see how soccer might be popular because that's all you have, but I grew up in the US playing soccer as did all my friends and the problem isn't that people in the US don't understand the game. It's fun to play but I always thought that if you really wanted to make soccer interesting for spectators you just need to get rid of goalies and introduce lane violations similar to basketball so somebody could maybe score once in a while. Otherwise it's just an hour or two of playing keepaway.
