I have been told that this is a major free way to get it. However, I haven't had the balls to do it myself... on the way to my local freeway onramp there are quiet a few signs up, ranging from "executive income- don't believe don't call" to "brazilian jujitsu" to "business cards" to "bridal show convention" and all kinds of misc stuff... I want to randomly call one and ask 2 separate things: Did you think you could just put a sign up with out the city code enforcement calling you? and How much traffic / results did you get from your sign? There seems to be 2 kinds of signs which work best: The lawn sign, which goes on grassy areas in between the curb and sidewalk, facing oncoming traffic. And the Telephone Pole Garage Sale type sign. Turns out certain color combos work best, with black on yellow being best, with neon coming in 2nd 3rd and 4th..... discuss.
