Okay, so if they are going to be in Ft. Lauterdale, FL and hitting only major cities, then what are those cities and what is the route? The big problems happen when you get to the Mississippi. What major venues do you string together to get you from Minneapolis to Seattle or Vancouver? Minneapolis to Denver is a long haul and Des Moine doesn't get you much closer, really. Add Omaha and Salt Lake City? Then going from San Diego to Texas becomes another chancy leg. Tucson to Albuquerque -- risky? And what cities to hit in Texas to keep it both short and get the max number of fans?
Try to cut it down and the travel distances become an issue. And forget flying...too expensive to get all the equipment from one place to the next (unless you are on tour with Maiden and have your own jet). That's the problem with North America -- you can't both get all the big venues and have a short tour.
