I'm glad the stadiums offer some semblance of a track menu, even if it's a poor navigation substitute, but when you use the stadium to go to a track, you need to come out of the track back in the stadium. Right now, you come out on the track and have to find the stadium again to get back to the list there, which makes for an annoying interface.

Personally, I'd consider this a bug, but since it might be on purpose instead of an oversight, I put it here where feedback goes.
