So the first official announcement from MiniUSA came this week, confirming the dates, starting Wednesday July 4th on the East Coast and finishing Sunday July 15th on the West Coast, cities as yet un-announced.
Official tagline: GoForth, Go West, Go MINI.
MC2 Magazine posted some possible tidbits of info, with noting there will be eleven cities as major stop-overs and of those five are new to the MTTS.
