At the end of the summer hopefully, or around Christmas time, I will be traveling from GRR to FLG to go down to school. Now I figured that I don't have a lot of stuff, so I can simply check my bags (since both CHI and FLG have checked baggage service) and highly doubt I'll have more than 3 to check (besides my two carry ons). My question is would I be able to get on at GRR with all this luggage, even though the Pere Marquette route doesn't have checked baggage anywhere along it's route? Or would I have to drive all the way down to Chicago in order to be able to check my bags. I know that my trip is actually in two legs, GRR to CHI, and then CHI to FLG, and so all I have to do is get to CHI. Would I just have to notify Amtrak/the conductor/car attendant ahead of time that I have extra bags, or would they not allow the extra bags to join me in my trip (which if I recall correctly, from GRR to CHI is only about 4 hours)
