What is the purpose of having that turnout. The Blue Jays voted to contract the Expos, it only opens Montreal and the Expos up to derision from Toronto residents re not supporting them in the first place, the Blue Jays were not playing the Expos in drag Nationals etc
The purpose is to spread the word, generate web hits, get on TV and get people talking about how Montreal got screwed by Selig, Loria and the powers-that-be in MLB. Yes the Jays voted to contract the Expos but Toronto is the nearest MLB city to Montreal and probably the majority of ex-Montrealers who have left Quebec in the past 30-odd years have settled in and around Toronto, which gives the group an opportunity to attract more people to this particular game to support the cause. That the Jays also have an expatriate Montrealer (and former Expos employee) as their GM doesn't hurt either. The Expos Nation people were even able to buy their tickets for this game at a special price right off of the Jays' website. So it clearly appears that the Jays are somewhat supportive.
To me there's little point in waiting for the Nationals to visit Toronto. That ship has sailed. But the Rays are a team that could be ripe for relocation. It's just like those latent Quebec Nordiques fans who travelled to Long Island to watch the Isles and Thrashers play a couple of years back. They were targeting teams that were in trouble financially, had no fan support, and which could be candidates for relocation. They wanted to let everyone know that they wanted back in the game. This is no different. If MLB comes back to Montreal, chances are it won't be an expansion team but rather a struggling team like the Rays.
I'd like to see this idea expanded to the West coast. Last time I went to an Expos game was back in 2003 when they played an interleague series in Seattle. Even though it was a mid-week series there was a ton of Expos fans who showed up from BC. Even a couple of weeks back when I went to Seattle to see the Mariners and Cubs play there were a couple of Expos caps and t-shirts among the crowd there. I think if something along the same lines were to be organized they could get a decent turn-out of Expos fans sitting in the bleachers at Safeco Field.
I went to see Tim Raines sign autographs at a minor league game here in Vancouver last week and every other person there seemed to be decked out in Expos gear. He was signing from before the first pitch until the middle of the 8th inning.
IMO any action which exposes Selig and his cronies to ridicule can't be a bad thing. I'm thousands of miles away from Toronto today but I'm still wearing my jersey. It may not help bring baseball back but it can't hurt.
