It's no secret that parking in the city is a bitch. So we've enlisted local parking guru and author of  Finding the Sweet Spot, David LaBua, to dish out weekly tips on navigating the ins and outs of city parking.

Says David:

Signs and curbs are straightforward and easy to understand, right?  Not always. And, the 1,932,416 parking citations issued last year confirm it. Have you ever gotten a ticket and felt that it was unwarranted, but after carefully reading (then re-reading) the wording on the sign or curb, you finally realized that you were indeed in the wrong? Quiz yourself on just how many restricted curbs are out there. We'll break down the answers right after your lunch break!

A) Green Zones

B) Blue Zones

C) White Zones
