When do you pull out the word "occasional"?
You likely use it in a casual way when talking about something you might do every now and then -- an occasional cupcake, an occasional trip to the roller rink. Occasional.
It's rarely used in the name of a large-scale, thousands-attend event, however. The Occasional Doo Dah Parade may be the singular exception, though, and use it the organizers do, flagrantly. No surprise, really: The Pasadena procession is billed as the "twisted sister" to the Rose Parade.
Why are they sometimes jokingly referred to as sibling parades? They both happen on Colorado Boulevard, yep, and they're both colorful, it is true, and they've both been around for a number of decades. (The Rose Parade about eight or so decades longer, give or take).
But there the similarities end. The Rose Parade is clockwork, while the Doo Dah kind of shows up on whatever date when it decides to show up. Hence "occasional."
You have to be asked or selected to be in the Rose Parade while you just need ten bucks and an Idea, capital I, to join the Doo Dah.
What constitutes an Idea, Doo Dah-style? We'd say "you name it" but that isn't quite broad enough. You can dress as an invisible man, roll around on a motorized couch, do cartwheels the whole route, or some combination of the three? Why? Because. That's all. Just because and nothing more.
It's free to watch, it may or may not start promptly at the announced time, oh, and it happens on East Colorado, not the part of Colorado where the Rose Parade rolls. You'll also want to be prepared since items are often flung into the crowds. Candy, hot dog buns, beads, even the random baked potato.
Yep, it may indeed be occasional, and a little unwieldy, but we'd call it a big Pasadena tradition. Is that okay, Doo Dah Parade? If we break that particular label out? We don't mean to go stuffy on you, but once you've been around for the better part of four decades, you're a Thing. Capital T.
