The Abita Mystery House

This quirky roadside attraction, located less than an hour north of New Orleans, offers a colorfully consolidated package of Louisiana eccentricity. It sprang from the mind of folk artist John Preble. Also known as the UCM Museum — Preble pronounces the initials “you see ’em” — the place trades in visual overload. The gargantuan Bassigator sculpture, a fish-alligator hybrid, sits in its own 26-foot-long shed. A seemingly crashed UFO sticks out of the side of an Airstream trailer. The star attraction remains Preble’s River Road diorama, a 30-foot miniature town with its own Mardi Gras parade, general store, mini golf course and New Orleans jazz funeral. And that’s just scratching the museum’s kitschy surface. See to believe, indeed.

Blaine Kern’s Mardi Gras World

Some families prefer to stay clear of New Orleans during Mardi Gras, yet the pageantry can still be intriguing. Mardi Gras World allows visitors a chance to get an up-close view of the giant, elaborate floats and props all year long without the potentially raucous crowds. You might see looming, blooming faux flowers, a cartoonish Moby Dick-size whale and massive mugs of everyone from Satchmo to JFK. The staff of craftspeople also can be caught in the act of putting together their next big creation. They’ll even let you slip on a Mardi Gras costume and take a bite of king cake.
