My favorites include:
Lyons Classic Pinball in Lyons,CO
Logans Arcade in Logans, Chicago, IL
Seattle Pinball Museum in Seattle, WA (i think it may have a different specific address)
and of course
www.madisonpinball.com 3 locations in Madison, WI
but I like this one because I am part of the group that started it all up and we now have 26 great playing games of all eras (EMs all the way up to FullT and Hobbit and they all play great). Please stop when you drive out to Logans and are heading west/North to visit LTG and then further west to Lyons on a great pinball road trip.
