I love misspam's ideas!
Seedy hotel rooms make for great photos, especially those with themes: colonial, western, or aquatic, to name a few.
And there's nothing like oddities along the way. Would you deny us the sight of Babe, Paul Bunyon's blue ox, or a giant mouse with cheese somewhere in Wisconsin?
Might I request funny regional menus as well?
Enjoy your adventure, and keep us updated!
