It’s a way for one Jeeper to tell another one “nice Jeep”....but it’s now out of hand.
I’ve seen Jeeps with 30, 40 or more on the dashboard......kinda dumb IMO.
When I get one I just throw it in the center console.
I only have one on my dash and that’s only because of my wife......and it’s a Trump duck.👇
