Saga of the Dragon Cult DM question - spoiler

[AstroCat]

What is a good way to get the PC's from Hadler's Gap to the start of DCC#17?

I know they are supposed to follow the wagon tracks, but the swamp is like 175-200 miles away and goes through Khor'Mot as well. Any ideas? Perhaps they got a glimpse of someone escaping in the same direction as the tracks or something?

Also, has anyone made any good maps to give to the players including the new locations added in this campaign. I am thinking at least for Crieste around Dundraville, Hadler's Gap, etc... I'm trying to figure out the best way to give the players a map of the areas they would know without giving away too much. I am thinking maybe something like Player Handout E ...

Thanks for the help!
