First off, from a Cubs fan, good luck tonight! I've been monitoring tickets for all of the teams that the Cubs could play during the postseason for several weeks, and the Blue Jays are the only ones that seem to have already sold World Series tickets to the general public. Can you confirm that?
I'm not sure how many Cubs fans would make the trip--they travel well and road game tickets will be cheaper than home tickets by a lot (probably double if the NLDS and NLCS are any indication). Cubs fans travel very well, and the first World Series since 1945 will get a lot of people to make the trip. However, with all the road games being on weekdays and the road games split between two trips, that will limit road travel.
I'm not trying to get ahead of myself, because as a life-long Cubs fan, I know how things typically end up going, but I just want to be prepared, because I will make the trip for all the games in Toronto if we make it, especially since Toronto is 1 of the 4 remaining MLB ballparks that I have not been to. I wasn't expecting to go this year, but maybe I'll get that opportunity in a few weeks!
Thanks in advance.
