I am just North of Lowell. I have someone coming out from the North side of Chicago to visit. Being North siders in the city they do not have a car. They can figure out how to get to the train station in Chicago. What are the rail options for them to come out as far as they can via train and for me to pick them up? It doesn't matter to me where in the Region I would have to go to pick them up but would obviously like the shortest drive for me but would balance that with safety and ease of travel for them.
