This is not a bad idea, it has a lot more merit than Eddie's idea. I still think the obvious answer is Princess park. It's fairly close to the city center, has room to expand without dealing with punt road, wouldn't result in ripping up the indigenous center and turning that into a 30-40k stadium wouldn't cost as much as Eddie's plan. Arden st is often proposed by North fans, but that has less space to expand as its sandwiched between two roads, whereas most of Princess park is surrounded by parkland. It would also mean that the three stadiums would be somewhat separated from each other, one to the north of the city, and the other two to the east and west of the city.
