I think this is where modern schools are a bit different. Newer schools are built like monoliths where every area can be accessed within itself. This wasn't the case being raised in Savannah for me. Savannah is also converting to this but not all schools are like this. Point taken. With that said, it should be a goal. My wife and I used to joke about how these schools looked like prisons. Maybe there was something to it.How does that work during class changes if there are trailers or other buildings? My high school was ~5,000 students across 3 buildings and 40+ trailers.
