People sometimes ride around 410/407 I forget where exactly. It wouldn't be legal though.
That's a crappy area, all rutted and washed out. The city had plans to purpose the area for enviromental trails and stuff like that but nothing has been done about it so far. There is plenty of signage that tells you not to be there. Unfrotunately if you live in Brampton you are probably going to have to trailer it to ganaraska forest or to a motocross track either gopher dunes or moto park. That's just been my experience and the places I go.
Does any one know what the fine is for riding behind the coke plant
Get a small dual sport. Lots of roads, paths - goat and otherwise, just a bit north of you.
Where would you suggest north of Brampton for a dual sport?
