People talk about the wonderful "sight lines" at IWS. I suppose that refers to a combination of distance from the field, height of the front row of seats, and slope of the seating area from there. (In old stadiums with a roof like CNE Stadium in Toronto there were pillars midway up the stands on the north side, so your sight lines were really bad if you happened to be sitting right behind one).
I don't find the game viewing experience at IWS any better than at Lansdowne Park or Taylor Field. McMahon Stadium is okay too. I haven't been to Molson Stadium so can't comment on that. I haven't been to Commonwealth Stadium in Edmonton either, but as many as 58,000 go to Esks games there, so they must not see it as so terrible to be an impediment to attending.
The only thing a track at a new stadium in Hamilton would necessarily affect is distance from the field. But height and slope can be adjusted to compensate for this, and even the distance can be reduced with retractable seats at the front if that's a desirable option. I don't see that this has to mean an inferior viewing experience. Of course the sight lines at any new stadium will be different from IWS, but maybe they'll be terrific too. I don't expect them to be the same, and I'm not afraid of the change.
Sure, it's nice to be close to the field at IWS, but that's about the only advantage the old stadium has going for it. Being a little further back to accommodate a track is not a big problem to me, and well worth doing if it means a new, clean, well-appointed, modern facility.
