Why, you get "Tour de Super Mario Bros.," of course.
A few months ago, Sean over at famicomblog.blogspot.com posted the hilarious "Tour d' Excitebike," which included numerous photos of bright orange Excitebike carts as they paraded around Fukuoka. Earlier this week, he continued the series with the aforementioned "Tour de Super Mario Bros."
Whereas the previous tour included trips to Fukuoka Castle and Hakata Bay, this one includes stops at Kyudai Central Library and some nearby planes and trains.
Go here to see more of Sean's Famicom-focused tomfoolery. (Trust me, it's worth a visit just to see his photos of North Korean propaganda from the 1980s.)
