dont be surprised if this does happen. I race at Ohsweken Speedway from time to time and have heard some scuttle butt about this there. There is a lot of money on the six nations reserve, dont kid yourself and those guys dont mind spending it. Ohsweken Speedway is an impressive place, but what rez money has done with Jukasa Speedway (former Cayuga Speedway) is truly outstanding.

If this was to happen in Ontario, I wouldnt be surprised at all if it was on the Six Nations Rez
