Yes. Elgin and Larkin both play at Elgin, and Streamwood and Bartlett play at Streamwood. South Elgin built their own field a few years back(used to play at Streamwood too) and play home games on Saturdays because they have no lights. It is all one district so I am guessing they are playing Streamwood because of the turf and lights.
The school is just 12-years old. I see a football field next to the school and plenty of land on Google Earth. I also see that they played one regular season home game at Streamwood H.S. The not-yet-official site for their playoff game this weekend is rumored to be Streamwood H.S. as well.
Why????
It's now the official site. Palatine vs South Elgin, 1:30pm Saturday at Streamwood High School.
Personally I'm glad because Streamwood's stadium is beautiful. Never been to South Elgin's, but it seems pretty "meh" and bereft of visitors grandstand.
If/when the Pirates get by South Elgin, next up might be Huntley...now THAT'S a beautiful stadium. Pirates won a playoff game there in 2014 and that place is nicer than alot of D2/D3 college stadiums. (Though I think that matchup would be at Palatine based on Huntley being home in first round)
