I saw another few today, and I have to say that I think it's pretty..odd. I started seeing it about maybe mid-summer last year, mostly on the ridiculously wealthy SUVs in Frontenac, a wealthy suburb of St. Louis. I actually recall seeing 4 in a row parked in front of Saks ALL with these large monograms in pink vinyl stuck to the middle of the back window. It's started to expand into the back windows of the "less ridiculously wealthy" population.
Am I the only one that thinks they look silly and make no sense? Especially if you drive like shit, which many people in this city are prone to do, why would you want your initials on your vehicle? Aside from making sure anyone who's ever been around you in traffic to avoid you like the plague in the future.
