Agreed on the tennis, I get the whole privacy thing but why make it so hard for parents to watch ??
From the tennis courts in our town, I would think it is lack of space for any type of viewing area and aesthetics. Either they stick them in a very small area with no room for any type of viewing stands or they try to hide them with landscaping which obscures any sight lines. Most schools/school sports do not make it easy for the parents to come watch - with the exception of football which is all about the spectator turn out at the weekly social event.
Now that you mention it, both of the city courts that I have seen are courts surrounded by chain link fence. There are no bleachers anywhere. It is just as if the courts were made only for the players. And for a recreational court, that generally makes sense . . . except for child players, where do the parents sit?
At high school level, I think the lack of student and parent spectating is sad. Though, except for football, I can't say it was any better in my day.
Football is the only sport with a decent crowd, and even that is sometimes very low.
Basketball is another sometimes low one. In the winter, I would rather be indoors in the warm gym, than outside in the cold and wind, watching soccer.
I shot at a Saturday Lacrosse game, where work would normally not be an issue, yet the parent attendance was sadly low.
If it is a road/away game, attendance is even worse.
Now that I think of it, badmiton is another sport, where there is NO space for parents to spectate. They use the entire gym floor, with the bleachers pushed back to the closed position. Though I think badmiton was a later sport that was shoehorned into the gym.
Though IF the school wants to boost parent participation, and funding of the booster club, they should design the facilities in a way for the parents to be able to watch their kids. Some bleachers, even small, is better than none. But of course the school designers know more than I do. And we are stuck with whatever the designers did many years/decades ago. To be fair, some newer sports probalby had to be "shoehorned" into the campus.
BTW, I've used Google Earth and the school map, to do advance recon of schools, before I go there. That helps me to find the various sport facilities in a big campus, and figure out where to park. The gym however is harder/impossible to find via a satellite picture, so I have to use the school map. Even so, I have had to do advance recon on foot, to check out a venue.
