Love 'em even if a few games get scuttled from time to time.
Or one tunnel only as some people are playing.
Maybe an Email to the original publisher will help.
Thanks, we did think of the one tunnel possibility but it seemed to increase the chance there was no appropriate city available by quite a bit. I could see it working in most cases though.
I believe one of the Lookout reps frequents the forums for their games here on BGG, but I will email them in a couple days. Thanks for the suggestion.
