INORITE? Some of them, when you enter the street, it's sitting about 2 planks away from you. Others you have to go over every freaking inch of the street. I've found it's helpful to zoom out when QQ hunting. :)

I usually take one pass before I zoom out. It depends on my patience level that day.

I missed one on a fox preserve once. That was embarrassing.

LoL, Smlarg!! Yeah, there have been a couple that were "behind" me when I entered the street. I'd get to the end, click the next sign, and think "nooooooo, I forgot to get the QQ!"
