Munich Roos need a new football playing ground

After playing Aussie Rules on the Hirschgarten for the past 12 years without any problems, all of a sudden the Ordungsamt have told us that we can't play there anymore. The ground was too small anyway and we've had a bit of a look, but haven't found anything suitable yet - but now it's somewhat critical to find something ASAP.

We basically need an oval ground that's a minimum of 150m long and 80m wide. Bigger would be better, but those are the minimum dimensions that would work. As most of the players have no cars, it needs to be close to public transport - it doesn't matter if it's out of Munich a bit, as long as it's near an S-Bahn and easy to get to. Preferable would be a sports-club with change rooms, where we could play across 2 or 3 soccer pitches, but any open grassy area will do. Obviously, as it's a contact sport, the ground can't be too hard, have rocks on it, or goal posts or a footpath or trees or anything else on the playing surface.

If anyone knows of a suitable place, then please let me know.

Just one PM suggesting a couple of grounds so far and I'll go and check those places out. If anyone else has any ideas, then please let me know. Maybe there's a big open field out of the city a bit, which someone here lives or works near that they can suggest. As I said, as long as it's not too far from public transport (preferably U-Bahn or S-Bahn), then it could be suitable.

We're pretty desperate to find something.

Thanks.

EDIT: I re-edited the title. We're still fine to train where we always have, at the Hirschgarten. We need a new ground to play games on.
