NSO would be a good option for a number of reasons.
1. Next closest to manly
2. Close to the city and even better on the way home for a lot of northern beaches residents
3. Gives a gig to one of the nicer grounds around Sydney
4. Will let Rhino relive the good old days of manly winning at north sydney oval
The other option is if we can score the 100K deal a game like souths did to play at homebush. Outside of that we will hurt but from reports and posts it seems that should only 1 person turn up we will be financially well off from the broncos.
