I'm sure it was to clear passage on the street for July 4 but I didn't see much traffic on Grand that day (July 4). I walked by there 3 different times and there wasn't much traffic the times I saw, which was in the later afternoon twice, then after the big fireworks show was over, around 9:30. At that time when everyone was leaving, traffic on the other streets was thick but Grand was empty. I took photos. Obviously though L.A.Beaches and Harbor (the responsible party) expected traffic. Point is, it would be so easy for anyone to miss those Tow signs, especially if they come to the beach fairly often and park there -- they wouldn't have expected tow signs. So easy to overlook. They're red and white just like the other signs. Of course we all need to check the signs, but the consequences are too brutal for a simple oversight. I'm thinking of families who might have driven some distance to get there, for instance. Happy 4th.  The tow signs should be more conspicuous, considering the damage towing does to people who, lets face it, haven't done much wrong. It's way out of proportion. Since it would be too expensive to redo the tow signs, they need to put stickers on them to make them harder to miss. For instance: a different color that makes them stand out from the other regular red + white signs; and/or the word "Caution"; and/or a picture of a tow truck.
