If you’re coming to Game 1 tonight against Denver, give yourself a little extra time and bring a little extra money for parking. The finale of “American Idol” is going on across the street from Staples Center and the streets are clogged with “Idol” fans. Parking at the Convention Center garage is almost gone. Plus, I forked over $25 instead of the usual $12. Can you say, price gouging, boys and girls? Anyway, you’ve all been warned.
