It's not that weird if you stop and think about it, and crying is a bit hyperbolic?
I'm sure Sela and the club will put on a hell of a show, but there are going to be things a single event will find harder to achieve that an open top bus through the city could and one of those is proximity to the cup and players (though likewise I'm sure the event will do things that you obviously couldn't with a bus tour).
Hopefully it's class, I'm sure it will be, but it's fair enough if people have been thinking about this day for decades and for whatever reason the celebration event is going in a direction that seems like it'll be tough to ensure everyone can get reasonably up close to the players and trophy. Maybe it's a lack of imagination on my part, but I don't see how you can do that to the same degree as you could a bus tour where you're a few metres away at the side of the road. Hopefully it is a lack of imagination from me and this time next week this thread will be full of posters reporting how much they loved it and how close they were able to get.
This forum has absolutely got previous on your last point, I just don't think it's a fair stick to beat the people who are a bit disappointed in this case, at least until more details emerge.
